Background/aim: Lost alveolar bone is commonly restored by distraction osteogenesis or bone blocks for substantial vertical bone augmentation (VBA), that is applied in conjunction with a barrier system. This study was performed to determine whether volume control of a three-dimensional (3D) printed nylon cap in the rat calvarial partial thickness bone defect would induce qualitative and quantitative differences in vertical bone regeneration.
Materials And Methods: A rat calvarial partial thickness bone defect was prepared and the 3D cap covered the defect to induce VBA, while the control group was left without cap placement. After six weeks the animals were sacrificed, and the calvaria were prepared for micro-CT (μCT) and histology.
Results: Quantitative μCT results showed that our cap system has significant osteoconductive properties, and the histology slide revealed new bone filled inside the cap.
Conclusion: The results clearly showed that this system was successful for VBA in a research animal model.

Background: The treatment of mandibular angle fractures remains controversial, particularly regarding the method of fixation. The primary aim of this study was to compare surgical outcomes following treatment with 1-plate versus 2-plate fixation across two oral and maxillofacial surgery clinics. The secondary aim was to evaluate associations between patient-, trauma-, and procedure-specific factors with postoperative complications and to identify high-risk patients for secondary osteosynthesis.

The nerve distribution in the mandible was described in only one report which showed an increase in nerve distribution density moving from the alveolar crest toward the inferior alveolar nerve. However, no previous reports have focused on the nerve distribution density in the maxilla.

Management of class III malocclusion in patients with cleft is geared toward improving the maxillary position with maxillary protraction therapy with or without bone anchorage. This study aims at evaluating the effects of bone-anchored maxillary protraction (BAMP) and tooth-anchored maxillary protraction (TAMP) appliances in patients with cleft lip and palate (CLP).

Background: Certain 3D interrelationships between adjacent implants can potentially predispose to prosthetic and biological complications.
Materials And Methods: Patient records with adjacent dental implants were assessed to evaluate the effects of vertical, horizontal and angulation interrelationships between splinted compared to non-splinted implant restorations on the occurrence of biological and prosthetic complications. Data on patient- and implant-related variables were collected at baseline (T1) during prosthesis placement and at the last follow-up appointment (T2).

Statement Of Problem: Whether the unfavorable crown-to-implant ratio of extrashort implants and the use of splinted versus nonsplinted crowns affects marginal bone loss and implant survival remains unclear.
Purpose: The purpose of this split-mouth randomized clinical trial was to evaluate the effect of splinting on survival rates and clinical and radiographic parameters associated with prostheses supported by extrashort implants in the posterior region of atrophic mandibles over a 3-year follow-up period.
Material And Methods: Sixty extrashort implants (5 mm in length) were placed in 10 participants.
