The ability to provide high-quality complete dentures is a key skill for the GDP. The increasing prevalence and utilisation of implant-supported overdentures has opened the possibility of a wide variety of treatment options to support patient care, while also creating the need for primary care practitioners to have a greater awareness of commonly used prosthetic attachments.A thorough understanding of the advantages and disadvantages of implant-supported overdentures is essential to ensuring appropriate treatment planning, consent and maintenance. This two-part series explores various aspects of implant-supported overdentures including assessment of the patient, treatment planning, different attachment systems and maintenance requirements.Part one will explore availability of implants in the NHS, the commonly available implant attachment systems, including their relative advantages and disadvantages.

INTRODUCTION
Complete dentures (CDs) have been associated with substantial problems regarding edentulous patient's function. Denture adhesives seem to be useful adjuncts to improving retention and stability.
METHODS
A clinical study was undertaken to investigate the effect of a denture adhesive (DA) on function in complete denture wearers along with the quality of their CDs. Thirty complete denture wearers participated in the study. The first phase of the experimental procedure comprised 3 groups of measurements performed at 3 distinct time points: the initial measurement (T1), a 2nd measurement after 15 days of DA daily application (T2), and a 3rd measurement following a 15-day washout period (T3). The second phase consisted of the follow-up measurements. The measurements included: recording of relative occlusal force (ROF), distribution of occlusal contacts (DOC) and center of force (COF) using the T-Scan 9.1 device and functional assessment of dentures using the FAD index.
RESULTS
The DA use induced a statistically significant increase in ROF (p-value=0.003) and decrease in COF (p-value⟨0.001) and DOC (p-value=0.001). The overall FAD score significantly improved (p-value⟨0.001).
CONCLUSIONS
The use of the DA improved the occlusal force, the distribution of occlusal contacts as well as the qualitative characteristics of CDs.

We report a case in which a patient was suspected of developing pneumonia due to wearing dentures that were immersed in a storage solution contaminated with 3.0 × 10 colony-forming units (cfu)/mL of Burkholderia cepacia. It is highly possible that the contaminated denture solution entered the trachea and caused the pneumonia, possibly due to the prolonged supine positioning of the patient. We demonstrated that B. cepacia isolated from the sputum and B. cepacia isolated from the denture storage solution had the same DNA fingerprint, and that the patient recovered from pneumonia after stopping the use of dentures. These findings suggest the storage solution as the main source of infection.

Lack of adequate retention, support, and stability in the complete denture can be attributed to a poor fit or incorrect shape of the polished surfaces. This article presents a case using the neutral zone technique effectively with the fabrication of computer-aided design and computer-aided manufacturing (CAD-CAM) record bases in an edentulous patient with severely resorbed alveolar ridges and discusses the overall treatment steps and clinical implications of this technique. A stable neutral zone and an accurate jaw relation were recorded using CAD-CAM record bases and stability of complete denture was optimized by arranging denture teeth and reforming polishing surfaces in the neutral zone. A new complete denture was fabricated for a patient with atrophic alveolar ridges by a technique utilizing the neutral zone with CAD-CAM record bases.

BACKGROUND
It is difficult to maintain complete dentures during meals in place. This in vitro study aimed to assess changes in denture retention between rest and function using denture adhesives and oral moisturizers in an oral cavity model.
METHODS
The following test samples were applied between the palatal plate and the edentulous jaw ridge model: denture adhesive, denture adhesive for dry mouth, oral moisturizer, and denture moisturizer. The retentive force was measured under two conditions: at rest while immersed in water and during function with a 2.5-kg load applied. The plate was pulled perpendicular to the occlusal plane and the retentive force was measured using a digital force gauge.
RESULTS
Under dry conditions, denture adhesive for dry mouth and oral moisturizer had a significantly higher retentive force than denture adhesive and denture moisturizer. After 30 min of immersion in water, the retentive force of the denture adhesive increased while that of the oral moisturizer decreased. After 30 min of function, the retentive force of the denture adhesive and denture adhesive for dry mouth remained high, while that of the oral moisturizer and denture moisturizer significantly decreased. Between rest and function, the retentive force of the denture adhesive and denture adhesive for dry mouth was high, and that of the oral moisturizer was low.
CONCLUSIONS
Immediately after use, denture adhesive for dry mouth exhibited high retentive force, but retention gradually decreased due to its water content.

Review
INTRODUCTION
Dentures are worn by 20% of the United Kingdom population for both physical and psychological symptoms associated with tooth loss. However, significant morbidity and mortality can result if dentures are swallowed or aspirated. This 10-year review investigated the development of complications following denture aspiration or ingestion, and identified key learning points.
METHODS
The Medline database was searched for cases of denture ingestion or aspiration from October 1, 2009, to October 31, 2019. Search terms included "dental prosthesis, denture, dental plate, bridge and false teeth" and "swallow, ingest, eat, aspirate and inhale." Potential factors influencing the development of complications were assessed (hollow viscus perforation, fistula formation, abscess, bowel obstruction, necrosis, hemorrhage, and airway obstruction). Statistical analysis was performed using χ and Pearson correlation tests in R Studio. No ethical approval was required.
RESULTS
Eighty-five patients were identified from 77 case reports. Fourteen articles were excluded due to insufficient information. Complications were documented in 37.6% (n = 32) of patients with 2 cases resulting in death. Duration of symptoms over 1 day ( = .005) and delayed removal beyond 4 days post-ingestion ( = .017) was significantly associated with increased rates of complications. There was no significant association between complication rate and patient age, denture type, level of impaction, or radiolucency.
CONCLUSION
Denture aspiration or ingestion can have serious consequences. Factors impacting complication rate revolve around early recognition and treatment. Clinician awareness of the potential risks of dentures is paramount to early diagnosis. We recommend early intervention to reduce the morbidity associated with this unassuming device.

Review
STATEMENT OF PROBLEM
Prosthetic rehabilitation, especially with removable complete dentures (CDs), can contribute to speech problems, although the prevalence of the problem is unclear.
PURPOSE
The purpose of this systematic review was to examine the influence of implant-supported fixed complete dentures (FCDs), implant-supported overdentures, and removable CDs on speech articulation disorders in patients with at least 1 completely edentulous jaw.
MATERIAL AND METHODS
This study was prepared according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and registered in the International Prospective Register of Systematic Reviews (CRD42020182705). The PubMed/Medline, Embase, Web of Science, Scopus, Latin American and Caribbean Health Sciences, Brazilian Clinical Trials Registry, and Cochrane Library databases were searched through April 2020 to identify clinical trials comparing maxillary and/or mandibular implant-supported dentures with removable CD use in terms of speech articulation in participants with at least 1 completely edentulous jaw. The risk of bias of selected studies was assessed with the Joanna Briggs Institute critical appraisal tools, and the quality of evidence was tested by using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
RESULTS
Initially, 2586 articles were identified, and their titles and abstracts were read. Sixteen articles were read in full, and 8 studies (4 paired clinical trials and 4 cross-sectional studies) were included in this review. In total, 290 prosthesis users aged 29 to 90 years, approximately 44 of whom had hearing difficulties, were included. Four studies had a low risk of bias, and 4 studies had a high risk of bias. Distortions of the /s/ phoneme were observed more often in the first 6 months of maxillary FCD use than with removable CD use. Speech articulation did not differ between mandibular FCD and removable CD users. The quality of evidence for speech articulation disorders was low.
CONCLUSIONS
Given the low quality of evidence on speech articulation disorders, further research on speech articulation disorders in prosthesis wearers is needed.

Objectives: Patients with xerostomia manifest various clinical signs of oral dryness, which has an impact on oral functions and wearing of dental prosthese?s, but the evidence of xerostomia-related changes in denture performance is unsatisfactorily documented. The purpose of this systematic review was to evaluate whether the available literature can answer the focused question "Is there an association between xerostomia and decreased denture performance among patients wearing removable dentures?" Data sources: Indexed databases were explored without time or language restrictions up to and including March 2019. All levels of available evidence including experimental studies, case reports, and case series were searched using different combinations of the following keywords: saliva, xerostomia, dentures, personal satisfaction, quality of life, oral dryness, and oral complaints. Nine studies were included for qualitative synthesis. Overall, five studies had a cross-sectional design and four studies were case-control studies. In these studies, the number of participants ranged between 35 patients and 493 patients with mean ages ?from 56 to 82 years; 66% of the patients were completely and 34% were partially edentulous.
.
Conclusion: All studies included patient satisfaction with dentures and recorded the presence of oral dryness. Six out of nine studies demonstrated that xerostomia is significantly associated with the decreased performance of removable dentures. Although the available evidence lacks feedback from randomized, controlled clinical studies, it implies a negative impact of oral dryness on specific denture functions such as speaking, chewing, and retention, which affects both complete and partial denture wearers.Topics: Aged; Aged, 80 and over; Cross-Sectional Studies; Denture Retention; Denture, Complete; Denture, Partial; Humans; Mastication; Middle Aged; Patient Satisfaction; Quality of Life; Xerostomia

Clinical Oral Investigations Apr 2022To assess the sociomedical and oral factors affecting masticatory performance in a community-dwelling older population.
OBJECTIVES
To assess the sociomedical and oral factors affecting masticatory performance in a community-dwelling older population.
MATERIALS AND METHODS
Community-dwelling persons over 60 years were investigated using medical and dental oral interviews, oral and denture examination (natural teeth, tooth mobility, number of occluding tooth pairs, and removable dentures' prevalence and quality), and evaluation of masticatory performance using a mixing ability test.
RESULTS
A total of 130 participants with a mean age of 73.9±8.5 years were recorded. Fifty-eight (44.6%) used various types of removable prostheses. Twenty were edentulous and used a pair of complete dentures. Univariate analyses revealed statistically significant associations (p≤0.05) between masticatory performance and aging, marital status, subjective chewing ability, use of removable dentures, use of various combinations of complete dentures, pain caused by maxillary denture, number of teeth, tooth mobility, posterior chewing pairs, all chewing contacts natural or prosthetic, retention of mandibular partial dentures, and dentures' occlusion. The multivariable quantile regression analysis revealed that fewer natural teeth (95% CI: -0.02-0.01, p<0.001), being edentulous and using a pair of complete dentures (95% CI: 0.09-0.35, p=0.001), and larger percentage of severely mobile teeth (95% CI: 0.07-0.82, p=0.020) were associated with lower masticatory performance.
CONCLUSIONS
Poor masticatory performance in older adults was associated with fewer teeth, being edentulous and using a pair of complete dentures, and increased prevalence of severe tooth mobility.
CLINICAL RELEVANCE
Retaining the natural dentition and preventing and treating periodontal disease are important measures to maintain masticatory performance in older adults.

The European Journal of Prosthodontics... Feb 2023The purpose of this questionnaire-based service evaluation was to assess patient satisfaction with complete dentures provided in a dental teaching hospital.
PURPOSE
The purpose of this questionnaire-based service evaluation was to assess patient satisfaction with complete dentures provided in a dental teaching hospital.
METHODS
Patients completed the self-administered questionnaire before, immediately after, and 2-months following provision of new complete dentures. The questionnaire consisted of the following sections: Patient characteristics, current denture history and satisfaction with the fit of upper/lower complete dentures, chewing ability, speech, and aesthetics. Descriptive analysis, chi-square test, student t-test, and 2-way-ANOVA were performed on satisfaction levels pre-and post-treatment to assess denture fit, chewing ability, speech, and appearance. Age and gender-wise satisfaction levels along with correlations and associations between patient satisfaction levels and various factors were assessed.
RESULTS
147 participants, including 91 males (61.9%) and 56 females (38.1%) completed the study. A statistically significant improvement in satisfaction scores was seen post-treatment in all domains (p⟨0.05), with most respondents showing great satisfaction. Overall, satisfaction levels were: Upper complete denture fit (82%), appearance (87%), speech (67%), chewing ability and lower complete denture fit (39%). A strong positive correlation was observed between the number of previous dentures used and patient satisfaction with upper denture fit (R=1).
CONCLUSION
Denture replacement positively impacts the satisfaction of patients and improves complete denture acceptance.
