Materials And Methods: A total of 78 partially edentulous patients in the posterior mandible were recruited for the study (n = 26/group). Group 1 served as the control group and received two dental implants to support a three-unit FPD.

The Effects of Maxillary Expansion on Late Alveolar Bone Grafting in Patients With Unilateral Cleft Lip and Palate.

Purpose: The purpose of this study was to answer the research question of whether maxillary expansion provides enough postgraft stimulation to decrease the volume loss of alveolar bone grafts in patients with cleft lip and palate (CLP) who missed the appropriate treatment time.

Materials And Methods: This study was designed as a prospective controlled clinical trial. Thirty patients in the permanent-dentition stage with unilateral CLP were divided into 2 groups: In group I (mean age, 19.

Short Implants Versus Standard Implants: Midterm Outcomes of a Clinical Study.

Introduction: The aim of this study was to evaluate the midterm survival rate, marginal bone resorption (MBR), and stability of short implants and to compare the results with standard length implants.

Materials And Methods: A total of 38 patients were included. In total, 147 implants (Nucleoss Implants, Izmir, Turkey) were placed (86 short implants and 61 standard implants).

Histomorphometric Evaluation of Bone Formation in Peri-Implant Defects Treated With Different Regeneration Techniques: An Experimental Study in a Rabbit Model.

Purpose: The aim of this study was to investigate the healing of artificially created peri-implant circumferential bone defects using three bone-regeneration techniques.

Materials And Methods: Rabbit tibias (24 rabbits), in which bone defects (9-mm diameter, 4-mm depth) were created and implant beds (3-mm diameter, 6-mm depth) were prepared in the middle of the created defects, were used as the experimental model. Dental implants (3.

An uncommon disorder with multiple skeletal anomalies: Gorlin-Goltz syndrome.

Gorlin-Goltz syndrome is an uncommon disorder transmitted through autosomal dominant inheritance. This syndrome is characterized by multiple odontogenic keratocysts, along with congenital skeletal anomalies and basal cell carcinomas. A 16-year-old girl was admitted with a complaint of swelling on the lower jaw.

Anorganic bovine-derived hydroxyapatite vs β-tricalcium phosphate in sinus augmentation: a comparative histomorphometric study.

The choice of augmentation material is a crucial factor in sinus augmentation surgery. Bovine-derived hydroxyapatite (BHA) and beta-tricalcium phosphate (β-TCP) have been used successfully in sinus augmentation procedures. Choosing one of these materials for sinus augmentation is still controversial.

Effects of systemic zoledronic Acid administration on osseointegration of hydroxyapatite-coated and resorbable blast material surface implants in rabbit models.

Purpose: It is unknown whether zoledronic acid (ZA) interferes with initial bone healing at implant sites. The goal of this study was to examine the effects of systemic zoledronic acid administration on osseointegration of hydroxyapatite (HA)-coated and resorbable blast material surface (RBM) implants in rabbit models.

Materials And Methods: Twenty-eight male New Zealand rabbits (aged 6 to 12 months) were used in this study.

Leonard buttons: a reliable method of intraoperative intermaxillary fixation in bilateral mandibular fractures.

Purpose: To retrospectively audit outcomes of using Leonard buttons (LBs) as intraoperative intermaxillary fixation in conjunction with open reduction-internal fixation of bilateral mandibular fractures.

Patients And Methods: Seventy-seven patients were included in this study. The fracture reduction score was obtained from postoperative radiographs by use of 3-tiered scoring system.

Comparison of bovine-derived hydroxyapatite and autogenous bone for secondary alveolar bone grafting in patients with alveolar clefts.

Purpose: The aim of this retrospective study was to compare the long-term outcomes of secondary alveolar bone grafting (SABG) using bovine-derived hydroxyapatite versus autogenous bone.

Patients And Methods: The subjects in this study were 23 patients with unilateral cleft lip and palate (13 male, 10 female) who underwent SABG from 2004 through 2009. The patients were recalled and examined to evaluate the success of the long-term outcomes of SABG.

Direct current electric stimulation in implant osseointegration: an experimental animal study with sheep.

In an effort to obtain a high-quality bone-implant interface, several methods involving alteration of surface morphological, physicochemical, and biochemical properties are being investigated. The aim of our study was to increase the osseointegration rate and quality and decrease the waiting period of dental implants before loading by using a microelectric implant stimulator device. It imitates microelectrical signals, which occur in bone fractures described in terms of piezoelectric theory.

Comparative study of the osseointegration of dental implants after different bone augmentation techniques: vascularized femur flap, non-vascularized femur graft and mandibular bone graft.

Objectives: The purpose of this study was to evaluate the osseointegration of the dental implants placed into the mandible augmented with different techniques in pigs.

Material And Methods: Four adult domestic pigs were used. Horizontal augmentation of the mandible was performed in animals by using vascularized femur flap (VFF), non-vascularized femur graft (NVFG) and monocortical mandibular block graft (MG).

Effects of vitamin K1 on fluoride-induced bone changes in growing rats: a histomorphometric and radiodensitometric study.

The aim of this study was to investigate the potential effects of vitamin K1 supplementation on skeletal changes related to fluoride in growing rats. Forty male Wistar rats aged 4 weeks were assigned at random into three groups: high-dose fluoride (125 ppm) group; high-dose fluoride + vitamin K1 (0.2 mg/(g day)) group; and a control group.

Dexmedetomidine versus midazolam in outpatient third molar surgery.

Purpose: The aim of this study was to compare the use of dexmedetomidine with the use of midazolam during intravenous conscious sedation in third molar surgery.

Patients And Methods: Twenty healthy patients with symmetrically impacted mandibular third molars were included in this double-blind, crossover, randomized study. Either dexmedetomidine (group D) (4 microg.

Microbial analysis of the autogenous bone collected by bone filter during oral surgery: a clinical study.

Patients And Methods: Twenty-five patients who had asymptomatic fully impacted mandibular third molars bilaterally underwent surgical removal for prophylactic and orthodontic considerations. Immediately before surgery all patients rinsed with 10 mL of their assigned solution (chlorhexidine or sterile saline) for 2 minutes.
