Journal of Prosthodontic Research Feb 2024This systematic review examined the effectiveness of soft denture relining (SDR) materials.
PURPOSE
This systematic review examined the effectiveness of soft denture relining (SDR) materials.
STUDY SELECTION
A comprehensive search of MEDLINE, Cochrane Library, and ICHUSHI was conducted up to July 26, 2020. Target outcomes were patient satisfaction, oral health-related quality of life (OHRQOL), masticatory ability (MA), denture functional duration, residual ridge resorption (RRR), and microbial contamination. An organization specializing in literature searches performed the reference searches, and two reviewers independently selected the literature sources, extracted the data, and assessed the risk of bias. The reviewers resolved any disagreements concerning the assortment of literature sources through discussion. SDR included acrylic- and silicone-based materials, which were evaluated separately.
RESULTS
Reviewers selected 7, 5, 11, 1, 4, and 6 studies to assess patient satisfaction, OHRQOL, MA, functional duration, RRR, and microbial contamination, respectively. The results confirmed that SDR improved patient satisfaction, OHRQOL, MA, and RRR. However, the functional duration of SDR material is shorter than that of hard denture relining (HDR) or acrylic resin material. Furthermore, SDR material is more susceptible to microbial contamination in the long term. The risk of bias for the included studies tended to be high because of specific issues (difficulty in blinding SDR versus HDR).
CONCLUSIONS
For patients who wear complete dentures, SDR often provides beneficial outcomes such as pain reduction and recovery from MA. However, caution should be exercised regarding their use owing to insufficient functional duration and the possibility of microbial contamination during long-term use.

Comparative Study Meta-Analysis Review
OBJECTIVES
The purpose of this systematic review with network meta-analysis was to assess the comparative efficacy of various types of denture adhesives in complete denture patients.
MATERIAL AND METHODS
A search was conducted for trials published in Scopus, PubMed, and Cochrane Central Register of Controlled Trials from inception until July 2023 (PROSPERO: CRD42023451045). A network meta-analysis was performed to assess the comparative efficacy of different denture adhesive types and ranked using the Surface Under the Cumulative Ranking (SUCRA) system. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was used to assess the level of certainty of evidence.
RESULTS
Seventeen articles were included in the quantitative analysis. Cream denture adhesives significantly increased bite force in both incisal region (RR = 7.63[95%CI: 3.34, 11.91]) (P < .05) as well as premolar and molar regions (RR = 33.66[95%CI: 15.15, 52.16]). Cream adhesives significantly improved retention of dentures as assessed by the reduced number of denture dislodgments (RR = -5.35[95%CI: -9.93, -0.77]) (P = 0.022), Kapur's index of retention (maxillary denture) (RR = 0.80[95%CI: 0.18, 1.42]) (P = 0.012) and Kapur's index of retention (mandibular denture) (RR = 1.27[95%CI: 0.67, 1.87]) (P < .05). Powder adhesives significantly increased premolar and molar bite force (RR = 36.00[95%CI: 16.20, 55.79]) (P < .05) and Kapur's index of retention (mandibular denture) (RR = 1.54[95%CI: 0.58, 2.49]) (P = 0.002). None of the adhesives were statistically significant for remaining outcomes.
CONCLUSIONS
Cream and powder denture adhesives are effective in enhancing the retention of mandibular dentures (Kapur's index) and bite force in the premolar/molar region in complete denture wearers (moderate level of certainty of evidence).
CLINICAL RELEVANCE
Cream and powder denture adhesives are effective in improving the retention and function of complete dentures.

BACKGROUND
Sleep bruxism is a prevalent condition in dentistry practice, characterized by involuntary grinding or clenching of the teeth during sleep. Several therapies, including occlusal splints, have been used to manage sleep bruxism and temporomandibular disorders, including occlusal splints. This study aimed to compare the effectiveness of different occlusal splints in managing sleep bruxism.
METHODS
The PICO framework encompasses the characterization of the population, intervention, comparison, and pertinent outcomes. A comprehensive and systematic literature review was conducted on PubMed, Scopus, and Google Scholar to identify grey literature. The search specifically targeted scientific studies published before September 20, 2023. The Cochrane Collaboration Risk of Bias Tool assessed the accuracy of the included Randomized Control Trials (RCTs). The modified Newcastle-Ottawa Scale assessed non-randomized studies. Data were systematically extracted, synthesized, and reported thematically.
RESULTS
Out of the total of 808 articles that were evaluated, only 15 articles were found to meet the specified inclusion criteria. Adjustable splints, such as full-occlusion biofeedback splints, were more effective in reducing sleep bruxism episodes, improving patient-reported symptoms, and enhancing overall well-being. The impact of different occlusal sprints on electromyographic activity varies, and potential adverse effects should be considered individually.
CONCLUSIONS
This review provides valuable insights into the effectiveness of occlusal splints in managing sleep bruxism. The results of this study indicate that occlusal splint therapy is a viable treatment approach for sleep bruxism.

Review
This study aims to review surgical treatment in paediatric condylar fractures and describe different types of techniques performed, along with the results obtained from them. A retrospective review was conducted from records of paediatric patients (from one to 17 years old) who sustained fractures of the mandibular condyle and underwent surgical treatment from 2003 to 2023. The number of patients, age, location, and type of fracture, clinical and imaging examinations, treatment methods, intraoperative/postoperative complications, removal of osteosynthesis material, follow up and outcomes were recorded and analysed. A total of 68 patients with 79 fractures were identified. The most common fracture pattern was condylar neck fracture (61.1%). Of the 68 patients who underwent surgical treatment, one had a complication of minimal temporal paraesthesia and another patient had near-complete resorption of the condyle. A total of 55 patients (81%) reported normal dental occlusion, mouth opening (>35 mm), lateral excursions (7-8 mm), TMJ function, no pain, no deviation of the midline or the jaw, and no ankylosis. Thirteen patients (19%) developed an unsatisfactory result, nine patients (13%) had a jaw deviation on mouth opening, four patients (6%) had mandibular retrusion, and seven patients (10%) had signs of TMJ dysfunction. A total of 59 patients (87%) reported bone completely healed with no signs of bone abnormality; seven patients (10%) had shortening of the condylar neck and/or ramus. Surgical treatment can lead to good or excellent results for severely dislocated and displaced condylar fractures in children and can reduce the unsatisfactory results resulting from closed treatment.

Review
Mandibular advancement devices (MADs) remain a popular non-invasive treatment modality for the management of obstructive sleep apnea (OSA). However, the occlusal side effects from long-term therapy may result in poor patient compliance and patient drop-outs. Hence, knowledge of the possible side effects of these devices on occlusion is necessary. This article attempts to systematically review the evidence available in support of the possible long-term effects of mandibular advancement therapy on occlusion in adult sleep apnea patients. A detailed search was conducted for unpublished and published literature and their references in various electronic databases. A grey literature search was also performed. Studies until June 30, 2022, were selected. Randomized controlled trials, non-randomized trials, and cohort studies investigating the occlusal side effects of MADs for the treatment of snoring or OSA with a follow-up of at least four years were included. Study selection, data extraction, and risk of bias assessment were performed individually and in duplicate. The risk of bias was assessed by Cochrane tools for randomized and non-randomized studies. Fourteen studies were selected for the final qualitative analysis. The side effects reported were upper incisor retroclination, lower incisor proclination, decreased overjet and overbite, and change in the total occlusal contact area. The review concludes that long-term MAD therapy has statistically and clinically significant effects on occlusion.

International Journal of Paediatric... Jul 2024Ectopic eruption of the maxillary first permanent molar is a local disturbance that affects the development of the occlusion. (Review)
Review
BACKGROUND
Ectopic eruption of the maxillary first permanent molar is a local disturbance that affects the development of the occlusion.
AIM
To evaluate the occurrence of self-correction of maxillary first permanent molar's ectopic eruption and its predictive factors.
DESIGN
Five electronic databases and part of the gray literature were investigated. The risk of bias was assessed using the Newcastle-Ottawa scale and the certainty of evidence using the GRADE tool.
RESULTS
Four studies were selected: Three had a low risk of bias, and one, moderate. Evidence with a moderate level of certainty was generated, indicating a possibility of 47%-78% of spontaneous correction up to 7 years of age. Supporting the prognosis, whether reversible or irreversible, there was a positive correlation between the severity of the atypical distal resorption of the second primary molar, a higher magnitude of impaction, a larger eruption angle, and a bilateral occurrence with the irreversibility of the cases.
CONCLUSION
Spontaneous correction of the ectopic eruption of the maxillary first permanent molar is feasible and dependent on the severity of predictive factors. Early intervention is mandatory in irreversible cases.

Meta-Analysis
BACKGROUND AND OBJECTIVE
The genetic basis of dentoalveolar characteristics has been investigated by several studies, however, the findings are equivocal. The objective of this systematic review and meta-analysis was to evaluate the heritability of dental arches and occlusal parameters in different stages of human dentition.
SEARCH METHODS
Electronic databases PubMed, Embase, Scopus, Web of Science, and Dentistry and Oral Science Source were searched up to August 2023 without the restriction of language or publication date.
SELECTION CRITERIA
Empirical studies investigating the heritability of dentoalveolar parameters among twins and siblings were included in the review.
DATA COLLECTION AND ANALYSIS
Study selection, data extraction, and risk of bias assessment were performed independently and in duplicate by two authors and a third author resolved conflicts if needed. Joanna Briggs Institute's critical appraisal tool was used to evaluate the risk of bias among studies and the certainty of evidence was assessed using the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria.
RESULTS
Twenty-eight studies were included in the systematic review, of which 15 studies reporting heritability coefficients in the permanent dentition stages were deemed suitable for the meta-analysis. Random-effects meta-analyses showed high heritability estimates for maxillary intermolar width (0.52), maxillary intercanine width (0.54), mandibular intermolar width (0.55), mandibular intercanine width (0.55), maxillary arch length (0.76), mandibular arch length (0.57), and palatal depth (0.56). The heritability estimates for the occlusal parameters varied considerably, with relatively moderate values for crossbite (0.46) and overbite (0.44) and low values for buccal segment relationship (0.32), overjet (0.22), and rotation and displacement of teeth (0.16). However, the certainty of evidence for most of the outcomes was low according to the GRADE criteria.
CONCLUSIONS
Based on the available evidence, it can be concluded that the dental arch dimensions have a high heritability while the occlusal parameters demonstrate a moderate to low heritability.

Review
Restoration of hemimandibulectomy defects following tumour extirpation to restore oral function is a herculean task for practitioners. Prosthetic treatment alternatives available for rehabilitation of acquired hemimandibulectomy defects according to mandibular reconstruction type and extent (Cantor-Curtis classification) are unclear. This systematic review aims to assess the spectrum of prosthodontic rehabilitation approaches with regard to reconstruction type and extent of mandibular surgical defects. The databases incorporated for literature search were Google Scholar and Medline (PubMed). Relevant search terms for hemimandibulectomy and reconstruction with prosthetic rehabilitation were used. Two reviewers independently assessed the articles using eligibility criteria; published case reports and case series in the English language and depicting prosthodontic treatment modality of patients greater than 15 years were included. A total of 202 records were identified from the database search of which 19 duplicates were removed. The remaining articles were assessed for eligibility, and 55 articles (comprising 58 cases) were finally included in the study. This review revealed various prosthetic alternatives ranging from guide flange, twin occlusion, palatal ramp, conventional to hybrid partial and complete dentures to implant-supported prosthesis including a few innovative prosthetic approaches. This systematic review provides a plethora of prosthodontic rehabilitation approaches according to the extent of hemimandibular surgical defect and type of reconstruction. This will facilitate practitioners and prosthodontists in sequential treatment planning and management of hemimandibulectomy cases in their routine practice.

Journal of Dentistry Nov 2023To review the factors that influence the accuracy of the maxillomandibular relationship at maximum intercuspation (MIP) acquired by using intraoral scanners (IOSs).
OBJECTIVE
To review the factors that influence the accuracy of the maxillomandibular relationship at maximum intercuspation (MIP) acquired by using intraoral scanners (IOSs).
MATERIAL AND METHODS
A systematic search was performed using five databases: MEDLINE/PubMed, Cochrane, Embase, World of Science, and Scopus. A manual search was also completed. Studies assessing the factors that influence the MIP acquired by using IOSs were included and organized based on the analyzed factor. Studies were evaluated by applying the Joanna Briggs Institute Critical Appraisal Checklist.
RESULTS
Twenty-nine articles were included. Seven factors have been identified: IOS system, scan extension, edentulous areas, number, location, and extension of occlusal records, occlusal force, tooth mobility, and alignment methods. Nine studies evaluated the influence of IOS system. Four studies assessed the influence of the extension of the arch scan. Three studies evaluated the effect of edentulous spaces. Four studies agreed on the impact of the number, location, and extension of the occlusal records on the MIP accuracy. One study assessed the influence of the occlusal force, showing a smaller average interocclusal space with increased occlusal force. One study evaluated the influence of tooth mobility. Seven studies analyzed the influence of the alignment method on the MIP accuracy.
CONCLUSIONS
Most of the studies reported no difference on the MIP accuracy between half- and complete-arch scans. Areas with 2 or more missing teeth reduce the MIP accuracy. A bilateral and frontal record including 2 teeth or a bilateral posterior occlusal including at least 4-teeth is indicated for maximizing the MIP accuracy.
CLINICAL IMPLICATIONS
When a complete-arch intraoral scans is obtained, a bilateral and frontal record including 2 teeth or a bilateral posterior occlusal record including at least 4-teeth is recommended for maximizing the accuracy of the MIP. When a half-arch intraoral scan is acquired, a posterior occlusal record including at least 4-teeth is indicated for optimizing the accuracy of the MIP.

Clinical Oral Implants Research Sep 2023This review evaluated the effects of rehabilitation with implant-supported prostheses on the oral function of completely edentulous adults. (Meta-Analysis)
Meta-Analysis
OBJECTIVES
This review evaluated the effects of rehabilitation with implant-supported prostheses on the oral function of completely edentulous adults.
MATERIALS AND METHODS
Systematic literature searches were performed to identify records reporting on oral function in completely edentulous adults rehabilitated with implant-supported prostheses. Meta-analyses were performed on various outcomes including bite force, masticatory performance, muscle activity, mandibular movement/chewing pattern, and salivary flow.
RESULTS
5507 records were identified. Thirty studies qualified for data extraction and analysis. The kappa (𝛋) for the search and identification strategy ranged between 0.50 and 1.00. Meta-analysis was performed grouping the studies by outcomes and split by time points of 6-12 months, 12-36 months, and >36 months after implant therapy. The meta-analyses revealed a significant improvement in oral function of completely edentulous adults after rehabilitation with implant-supported prostheses at 6-12 months (Z = -4.895, p < .001; 95% CI: -0.703, -0.301; τ = .609; Q = 114.953, df = 17, p < .001; I = 85.2%), at 12-36 months (Z = -4.886, p < .001; 95% CI: -0.580, -0.248; τ = .908; Q = 280.611, df = 35, p < .001; I = 87.5%) and at more than 36 months (Z = -9.108, p < .001; 95% CI: -1.472, -0.951; τ = .019; Q = 7.918, df = 7, p = .340; I = 11.6%). The included studies demonstrated a low to moderate risk of bias.
CONCLUSIONS
This systematic review concluded that the oral function of completely edentate adults significantly improved with implant-supported/retained prostheses, even when only one jaw received implant therapy. Therefore, implant therapy should be promoted for edentulous adults to alleviate the shortcomings of conventional complete removable dental prostheses.
