INTRODUCTION
This in-vitro study investigated limitations of intra-oral scanners (IOS) in capturing palatal defects at decreased mouth openings. The trueness and precision of composite 3D-printed models from Cone-Beam Computed Tomography (CBCT) and IOS were measured.
METHODS
A partially dentate palatal defect model was scanned with IOS (3M™TrueDefinition) at various simulated mouth openings. Five silicone impressions were poured in gypsum. Scans were taken using 3M™TrueDefinition; Planmeca Planscan®, n=5 each. Model was scanned on two CBCT (PlanmecaProFace®; Accuitomo170®CBCT, n=5 each). Geomagic®Control2014™ was used to create composite-models merging CBCT with IOS. Thirty composite-models were 3D-printed. Trueness and precision were measured. Pearson Correlation Coefficients measured correlation between mouth opening and data capture. Data analysed using Kruskal-Wallis, Wilcoxon rank-sum, and ANOVA. Statistical significance inferred when p⟨0.05.
RESULTS
Mouth openings ⟨20mm, IOS didn't capture information of soft tissue. Increased mouth opening positively correlated with increased data capture(r=0.93, p=0.001). AccuitomoCBCT and TrueDefinition IOS composite-models had the highest (trueness) and [precision](median (IQR) 0.172 mm(0.062-0.426)); [mean [SD] 0.080 mm [0.008]]. Casts had the lowest results (median (IQR) 0.289 mm(0.119-1.565));[mean [SD] 0.338 mm [0.089]](p⟨0.001).
CONCLUSION
Mouth opening ⟨20mm resulted in insufficient data capture by IOS for clinical applications. Composite digital models showed promising trueness and precision results.

BACKGROUND
Patient safety is crucial in dentistry, yet it has received delayed recognition compared with other healthcare fields. This literature review assesses the current state of patient safety in dentistry, investigates the reasons for the delay, and offers recommendations for enhancing patient safety in dental practices, dental schools, and hospitals.
METHODS
The review incorporates a thorough analysis of existing literature on patient safety in dentistry. Various sources, including research articles, guidelines and reports, were reviewed to gather insights into patient safety definitions, challenges and best practices specific to dentistry.
RESULTS
The review underscores the importance of prioritising patient safety in dentistry at all levels of healthcare. It identifies key definitions and factors contributing to the delayed focus on patient safety in the field. Additionally, it emphasises the significance of establishing a patient safety culture and discusses approaches such as safety plans, incident management systems, blame-free cultures and ethical frameworks to enhance patient safety.
CONCLUSION
Patient safety is vital in dentistry to ensure high-quality care and patient well-being. The review emphasises the importance of prioritising patient safety in dental practices, dental schools and hospitals. Through the implementation of recommended strategies and best practices, dental organisations can cultivate a patient safety culture, enhance communication, mitigate risks and continually improve patient safety outcomes.

Bone quality, volume, height and width all play a pivotal role in dental implant stability, success and survival. A lack of adequate bone can be overcome with various bone grafting procedures. Dependent on many factors, including the amount of bone required, the site of implant placement, patient preferences and clinician factors; the type of bone grafting material and procedure undertaken can vary. Supplemental bone can be sourced from a variety of sources, including autogenous, allogenous and xenograft bone. Dependent on the source of the bone, it will have different properties in aiding bone formation, as well as being presented in different formulations, such as bone particles or bone blocks.The aim of this paper is to provide an overview of bone grafting indications, materials and types of bone grafting techniques that can be utilised to aid dental implant provision. It also discusses the properties needed to ensure optimal success of guided bone regeneration techniques.

Review
Posterior Crossbite is a common condition resulting because of transverse maxillary deficiency. The growth of the craniofacial complex finishes first in the transverse dimension, followed by sagittal and vertical dimensions. Conventional rapid palatal expansion (RPE) appliances are commonly used to correct transverse maxillary deficiency. Although RPE is efficient in correcting posterior crossbite, it results in dental side effects such as buccal tipping of maxillary molars, root resorption, bone dehiscence, and relapse. Mini-implant-assisted RPE has been introduced to increase the skeletal effects of expansion especially in patients with increased maturation and greater interdigitation of midpalatal suture. This article will review the biomechanics of RPE and mini-implant-assisted RPE. Additionally, the different designs of MARPE and the long-term clinical effects of expansion appliances will also be discussed in detail.

Review
STATEMENT OF PROBLEM
High-performance polymers including polyetheretherketone (PEEK) and polyetherketoneketone (PEKK) have been used as substitutes for metal frameworks in dental prostheses. However, the clinical performance of polymer-based frameworks is still uncertain.
PURPOSE
The purpose of this systematic review was to compare the clinical performance of PEEK and PEKK with that of metal frameworks for different dental prostheses.
MATERIAL AND METHODS
This review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Six databases and non-peer-reviewed literature (without language or follow-up restrictions) were searched for studies conducted before February 2022. Only clinical studies, either randomized clinical trials (RCTs) or nonrandomized clinical trials (N-RCTs), comparing the clinical performance of polymer and metal frameworks were included. The risk of bias and certainty of the evidence were assessed with the RoB 2.0, ROBINS-I, and GRADE. Biologic (plaque and gingival indices, probing depth, bleeding scores, implant stability quotient, marginal bone loss) and mechanical outcomes (ridge base relation, prosthetic marginal gap, and fracture) were assessed.
RESULTS
Only 9 studies (7 RCTs and 2 N-RCTs) were included, all with moderate to serious risk of bias and low to very low certainty of evidence. No meta-analysis was possible, but qualitative analysis revealed lower plaque and gingival indices, probing depth, and marginal bone loss, with higher survival rates for implant-supported fixed prostheses and overdentures fabricated with PEEK than for metal frameworks. No significant differences were found between groups for removable partial dentures. The marginal fit of PEEK frameworks was also better for single crowns. Three fractures were reported in the 3 PEKK fixed dental prostheses with cantilevers.
CONCLUSIONS
PEEK and PEKK seem to be promising materials for dental prostheses, with acceptable response from the periodontal tissue. However, further well-designed studies are necessary to better understand their clinical and long-term limitations.

Review
This case report presents a literature review and a case report of a full-mouth implant rehabilitation for a 65-year-old woman with a history of Bruxism. The patient's oral condition showed dentition with severe occlusal wear, extensive dental work, and missing teeth replaced with bridges and implants. The existing dental work was failing due to recurrent caries and the mechanical failure of long-span bridges. The unique aspect of the treatment presented in this report is the management of existing osseointegrated implants of different systems with different platform designs, which adds to the treatment's complexity. The existing implants were incorporated into the planned treatment, and other implants were added to support maxillary zirconia and mandibular hybrid full-arch prostheses. After 2 years of function, extensive wear was evident on the milled acrylic, even though an occlusal guard was used. New acrylic teeth were processed using the same milled titanium bar of the mandibular hybrid prosthesis, and the occlusal surfaces of the acrylic teeth were protected with gold onlays. The patient is seen regularly for maintenance every 6 months with no further complications. Careful evaluation, planning, and treatment execution are paramount in managing patients with a history of bruxism. Patients should be prepared and informed about possible mechanical failure and seen regularly for maintenance.

Review
At its core, endodontics is a specialty centered on saving patients' teeth. Nonsurgical root canal therapy and nonsurgical retreatment, arguably the "bread and butter" of endodontics, not only facilitate the preservation of the natural dentition, but in many cases, alleviate pain. Most patients arrive for endodontic treatment expecting symptom relief. A small percentage of these patients, however, experience just the opposite. Within 48 to 72 hours, these select patients experience worsening symptoms, including swelling and pain, and may wonder what mishaps may have occurred during their treatment. These symptom exacerbations are referred to as endodontic flare-ups and are well-documented in the literature. In most cases their occurrence does not reflect a lack of practitioner judgment or skill, but rather a biologic event resulting from a shift in the delicate balance of the bacterial communities and inflammatory events at the periapex. This article reviews the pathophysiology and treatment of endodontic flare-ups, thereby informing patient communication strategies surrounding these events, to preserve both the teeth in question as well as patient relationships.

Review
Dental implants are a regular feature in daily clinical practice and there is a need to undertake routine assessment and maintenance of implants and their restorations on par with that provided for natural teeth. Occlusal checks form an important part of the maintenance regime for preserving the integrity of implants, their restorations, and health of the peri-implant tissues. Implant restorations are subjected to the full characteristics and magnitude of occlusal forces, including those associated with parafunction. Compared with the periodontal ligament around teeth, the biophysical response to occlusal forces of osseointegration is different through the more rigid link of implant to bone and reduced proprioception. Risks attributable to occlusal forces primarily affect implant restorations and they are elevated in the presence of bruxism. The occlusal guidelines recommended by the literature are aimed at reducing these risks and regular assessment and maintenance of the occlusion is essential. A four-step sequence is presented to ensure that the annual occlusal checks include the patient's input and evaluation of restoration integrity, occlusal scheme, additional protection, and spatial changes.
