Does the modified inferior border osteotomy improve the surgical outcomes in bilateral sagittal split osteotomy?

Background: To investigate the effect of lower border osteotomy on the lingual split pattern and IAN in BSSO procedures.

Materials And Methods: The study comprised 32 patients (64 operated sides) who underwent bilateral sagittal split osteotomy (BSSO) due to dentofacial abnormalities between the periods of April 2021 and April 2022. In the mandible, 32 sides (the conventional group) received standard BSSO surgery, while 32 sides (the modified group) additionally received lower border osteotomy.

Which factors affect the lingual fracture pattern in sagittal split ramus osteotomy?

The purpose of this study was to elucidate the effects of mandibular anatomy and osteotomy technique on lingual fracture patterns in SSRO. The predictor variables were: length of horizontal medial osteotomy; type of border osteotomy; buccolingual width; and vertical length of the basal cortex. The outcome variable was the type of lingual split pattern.

PREEMPTIVE INTRAVENOUS IBUPROFEN AND LOCAL KETAMINE IMPROVE POSTOPERATIVE ANALGESIA FOLLOWING THIRD MOLAR SURGERY: A DOUBLE-BLIND, RANDOMIZED, PLACEBO-CONTROLLED CLINICAL STUDY.

Objective: To compare the efficacy of preemptive ibuprofen, local ketamine, and their combination in managing postoperative pain and trismus following third molar surgery.

Materials And Methods: One hundred patients were randomly divided into 4 groups. The Intrafen Group had their impacted third molars surgically removed under local anesthesia after receiving intravenous (IV) ibuprofen for preemptive effect.

Does the Posterior Bending Osteotomy in Bilateral Sagittal Split Osteotomy Affect the Condyle Position in Asymmetric Patients?

Purpose: To measure and compare changes in postoperative condylar position following bilateral sagittal split osteotomy in patients with asymmetry treated using a posterior bending osteotomy (PBO) and conventional methods (shaving of premature contacts).

Methods: Participants were randomized to either the PBO or conventional group. The inclusion criteria were the need for bilateral sagittal split osteotomy or bimaxillary asymmetric surgery (menton deviation >4 mm).

Evaluation of trabecular changes following advancement genioplasty combined with or without bilateral sagittal split osteotomy by fractal analysis: a retrospective cohort study.

Background: It is aimed to investigate whether there was a difference in radiographic changes in the operational areas between genioplasty alone and genioplasty combined with mandibular advancement and to evaluate the fractal dimension (FD) to assess trabecular changes after genioplasty surgery.

Methods: Preoperative-(T0) and postoperative-(T1) panoramic radiographs of 26 patients without any complications who underwent genioplasty combined with bilateral sagittal osteotomy and mandibular advancement or genioplasty alone were selected. In the panoramic radiographs of both groups, the genial segment, mandibular angulus, and surgical osteotomy line were examined using FD.

Comparison of the accuracy of pilot-drill-guided and fully guided implant surgery with dynamic navigation. In vitro model study.

The aims of the present study are to measure and compare dental implant deviations with fully guided and pilot-drill-guided protocols using dynamic navigation systems in polyurethane models. The pilot-drill-guided group was determined to be the study group and included 12 implant applications. In this group, the pilot hole was drilled with navigation guidance, and the procedure was completed freehandedly.

Evaluation of trabecular bone healing using fractal dimension analysis after augmentation of alveolar crests with autogenous bone grafts: a preliminary study.

Objective: The aim of this study is to evaluate bone remodeling after alveolar crest augmentation with autogenous bone grafts.

Methods: 50 patients who were applied augmentation due to alveolar deficiency were included in this study. Fractal dimensions were measured on the radiographs in the preoperative, postoperative, follow-up periods.

A comparative evaluation of parasymphyseal fracture fixation in edentulous patients performed using dynamic navigation systems and Herbert screws with the conventional two-plate method: A study on models.

Purpose: The investigators performed this study to compare the rigidity outcomes for minimally invasive fixation of edentulous mandibular parasymphyseal fractures without flap creation using Herbert screws with a dynamic navigation system and the conventional two-plate method.

Methods: The investigators implemented an in-vitro study design, and 20 polyurethane edentulous mandibular models covered with flexible plastic to simulate the gingiva were used. Parasymphyseal fractures were created in all models using a reciprocal saw.

Evaluation of the Pterygomaxillary Separation Pattern in Le Fort I Osteotomy Using Different Cutting Instruments.

Purpose: Pterygomaxillary separation (PMS) is considered the main reason for serious complications associated with Le Fort I osteotomy. The aim of this study was to evaluate whether a piezo surgery, ultrasonic bone scalpel, or conventional bur used in Le Fort I osteotomy has an influence on PMS patterns.

Materials And Methods: Using a retrospective cohort study design, we enrolled a sample composed of patients who underwent orthognathic surgery.

Is Ultrasonic Bone Scalpel Useful in Le Fort I Osteotomy?

Purpose: Safety and precision are 2 main goals in research to improve bone cutting in maxillofacial surgery. The aim of this prospective clinical study was to analyze the outcomes using an ultrasonic bone scalpel versus a piezoelectric surgical device and the conventional technique in a Le Fort I osteotomy.

Materials And Methods: We designed a prospective, randomized, single-blind cohort study.

Does Single-Dose Preemptive Intravenous Ibuprofen Reduce Postoperative Pain After Third Molar Surgery? A Prospective, Randomized, Double-Blind Clinical Study.

Purpose: The aim of the present study was to identify the preemptive analgesic effect of intravenous (IV) ibuprofen before and after mandibular third molar surgery.

Materials And Methods: We randomly divided 75 patients into 3 groups. Group 1 received IV ibuprofen 60 minutes before surgery and IV placebo (100 mL of saline) after surgery.

Effects of boric acid on bone formation after maxillary sinus floor augmentation in rabbits.

Purpose: Augmentation of the maxillary sinus floor with bone grafting is commonly used for successful treatment of edentulous posterior maxilla with dental implants, and it is essential to maintain good bone volume and quality for long-term success of dental implants. The aim of this experimental study was to investigate the local and systemic effects of boric acid on new bone formation after maxillary sinus floor augmentation (MSFA).

Materials And Methods: Twenty-four male, New Zealand rabbits were randomly divided into three groups with eight rabbits each, and bilateral MSFA was performed in each animal.

Closure of Oroantral Communication With Plasma-Rich Fibrin Membrane.

Oroantral communication (OAC) is the opening between the maxillary sinus and oral cavity. It may cause oroantral fistula or maxillary sinusitis if left untreated. The surgical closure of the OAC within 48 hours was recommended to avoid the complications like sinus infections.

Does Guided Bone Regeneration Prevent Unfavorable Bone Shapes in Distraction Gap?

Purpose: Complications related to distraction osteogenesis can cause degradation of newly regenerated bone. Additionally, an unfavorable shape of the regenerated bone at the distraction gap can reduce the quantity of regenerated bone. The aim of the present study was to report on the prevention of unfavorable shapes of regenerated bone using guided bone regeneration during distraction.
