Correlation between upper airway dimension and TMJ position in patients with sleep disordered breathing.

Objective: The goal was to perform a 10-year retrospective study on the correlation between sleep disordered breathing (SDB) and upper airway dimensions, as well as the relation between SDB status and TMJ position. The study also examined links between airway dimensions and TMJ position.

Methods: Patients were categorized into Control (n = 28) or SDB (n = 45).

Effects of deformation twinning on the mechanical properties of biodegradable Zn-Mg alloys.

To satisfy the property requirements for biodegradable medical implants, Zn alloyed with low levels of Mg (≤0.8 wt%) has attracted increased research interest. In the present study, deformation twinning was observed in tensile tests and twinning appears to have an adverse impact on ductility.

Evaluation of the first maxillary molar post-extraction socket as a model for dental implant osseointegration research.

Objectives: Published information regarding the use of rat jawbones for dental implant osseointegration research is limited and often inconsistent. This study assessed the suitability and feasibility of placing dental implants into the rat maxilla and to establish parameters to be used for dental implant research using this model.

Materials And Methods: Forty-two customized titanium implants (2 × 3 mm) were placed bilaterally in the maxillary first molar area of 21 Sprague-Dawley rats.

Estrogen Deficiency-Associated Bone Loss in the Maxilla: A Methodology to Quantify the Changes in the Maxillary Intra-radicular Alveolar Bone in an Ovariectomized Rat Osteoporosis Model.

The effects of estrogen deficiency on bone characteristics are site-dependent, with the most commonly studied sites being appendicular long bones (proximal femur and tibia) and axial bones (vertebra). The effect on the maxillary and mandibular bones is still inconsistent and requires further investigation. This study was designed to evaluate bone quality in the posterior maxilla of ovariectomized rats to validate this site as an appropriate model to study the effect of osteoporotic changes.

Flapless dental implant surgery: a retrospective study of 1,241 consecutive implants.

Purpose: The purpose of this study was to identify retrospectively the predictors of implant survival when the flapless protocol was used in two private dental practices.

Materials And Methods: The collected data were initially computer searched to identify the patients; later, a hand search of patient records was carried out to identify all flapless implants consecutively inserted over the last 10 years. The demographic information gathered on statistical predictors included age, sex, periodontal and peri-implantitis status, smoking, details of implants inserted, implant locations, placement time after extraction, use of simultaneous guided hard and soft tissue regeneration procedures, loading protocols, type of prosthesis, and treatment outcomes (implant survival and complications).

Serum bone formation marker correlation with improved osseointegration in osteoporotic rats treated with simvastatin.

Objective: Simvastatin has been shown to enhance osseointegration of pure titanium implants in osteoporotic rats. This study aimed to evaluate the relationship between the serum level of bone formation markers and the osseointegration of pure titanium implants in osteoporotic rats treated with simvastatin.

Materials And Methods: Fifty-four female Sprague-Dawley rats, aged 3 months, were randomly divided into three groups: Sham-operated group (SHAM; n = 18), ovariectomized group (OVX; n = 18), and ovariectomized with simvastatin treatment group (OVX + SIM; n = 18).

Application of autologous periosteal cells for the regeneration of class III furcation defects in Beagle dogs.

The aim of this study was to evaluate the healing of class III furcation defects following transplantation of autogenous periosteal cells combined with beta-tricalcium phosphate (beta-TCP). Periosteal cells obtained from Beagle dogs' periosteum explant cultures, were inoculated onto the surface of beta-TCP. Class III furcation defects were created in the mandibular premolars.
