Is Vitamin D Deficiency a Risk Factor for Osseointegration of Dental Implants - A Prospective Study.

Introduction: Early dental implant failure (EDIF) can occur even when optimal materials are used, surgical protocols are strictly followed and the quantity and quality of bone at the recipient site are sufficient. The existence of specific patient-related risk factors require an investigation into the regulatory mechanisms controlling bone metabolism, bone remodelling and bone turnover as well as serum Vitamin D. The implant stability quotient is used as a prognostic indicator for possible implant failure.

Using the Dermal Fat Graft as a Barrier Membrane in Unilateral Alveolar Cleft Grafting: A Randomized Clinical Trial.

Introduction: Alveolar cleft grafting is a surgical procedure that usually suffers from inferior results.

Methodology: The patients were divided into 2 groups; study and control. In the study group, the grafted site was covered with a dermal fat graft.

Treatment algorithm for velopharyngeal dysfunction in patients with cleft palate: a systematic review.

The aim of this study was to review current literature regarding the speech outcome of different techniques of surgical treatment of VPD in cleft patients, in an attempt to reach a treatment algorithm. A systematic review was done, by searching Pubmed, Scopus, and Web of Science electronic databases, following the PRISMA guidelines. Articles reporting speech assessment results of secondary VPI surgeries on non-syndromic patients with CP.

A rare complication of hemolacria after Le fort I osteotomy: a case presentation.

Background: Nasolacrimal duct obstruction (NDO) is a common pathology preventing the proper drainage of the tears, and its main symptom is epiphora. Secondary acquired nasolacrimal duct obstruction (SANDO) can be due to a variety of causes including infection, trauma, or neoplasms. It has been reported to occur with different forms of maxillofacial trauma, especially Le Fort II, Le Fort III, naso-orbital-ethmoidal, and orbital floor fractures.

The correction of asymmetry using computer planned distraction osteogenesis versus conventional planned extra-oral distraction osteogenesis: A randomized control clinical trial.

The aim of the current study was to evaluate the effect of the use of computer-guided surgical templates in association with mandibular distraction osteogenesis to correct mandibular asymmetry. In the study group a simulation process was conducted to restore the exact position of the chin skeletally by planning the osteotomy orientation, distractor vector, pin positions, and distraction distance calculation. The Control group was treated with conventional distraction in which an oblique osteotomy was done, and distraction was performed until the midline coincided.

The Effect of Bone Marrow Aspirate Concentrate Application on Distracted Bone Biomechanical Properties.

Background: This study was conducted to assess effect of bone marrow aspirate concentrate (BMAC) on enhancing biomechanical properties of distraction osteogenesis (DO).

Methods: Twelve rami of goats had distraction and were divided into test group (DO bone supplemented with BMAC) and control group.

Results: Assessment of bone-width showed nonsignificant (P = 0.

Novel Technique and Step-by-Step Construction of a Computer-Guided Stent for Mandibular Distraction Osteogenesis.

Introduction: Distraction osteogenesis is an integral part in management of mandibular defects associated with hemifacial microsomia and post-ankylotic mandibular defects. The most difficult part in distraction osteogenesis is the prediction of distraction vector and risk of injury to vital structures as inferior alveolar. The present study aimed to present 3-dimensionally constructed computer-guided splints in distraction osteogenesis to get an ideal vector and minimal risk of vital structures injury.

The Effect of Bone Marrow Mesenchymal Stem Cells Application on Distracted Bone Quality during Rapid Rate of Distraction Osteogenesis.

Distraction osteogenesis (DO) bone regenerate usually suffers from an inferior quality especially with rapid rate. This study was conducted to investigate the effect of mesenchymal stem cells (MSCs) application on different rates of distraction bone quality. Twenty-four goats were divided into group A with standard DO and group B with rapid distraction osteogenesis (RDO) both aided by MSCs.

Cone Beam Computed Tomography Analysis of Oropharyngeal Airway in Preadolescent Nonsyndromic Bilateral and Unilateral Cleft Lip and Palate Patients.

Objective: The objective of this study was to assess the volume, area, and dimensions of the oropharyngeal airway (OPA) in a previously repaired nonsyndromic unilateral cleft lip and palate (UCLP) versus bilateral cleft lip and palate (BCLP) patients when compared with noncleft controls using cone beam computed tomography (CBCT).

Design: This was a retrospective case-control study.

Setting: The Cleft Care Center and outpatient clinic that are affiliated to our faculty were the settings for the study.

Effect of Mesenchymal Stem Cell Application on the Distracted Bone Microstructure: An Experimental Study.

Purpose: Distraction osteogenesis (DO) is a surgical technique used to regenerate bone. The aim of this study was to improve bone quality and quantity during DO by the addition of mesenchymal stem cells (MSCs).

Materials And Methods: The study was conducted on 12 goats assigned to a study group or a control group.

Cone-Beam Computed Tomography Analysis of the Nasopharyngeal Airway in Nonsyndromic Cleft Lip and Palate Subjects.

Objective: To assess the nasopharyngeal airway volume, cross-sectional area, and depth in previously repaired nonsyndromic unilateral cleft lip and palate versus bilateral cleft lip and palate patients compared with noncleft controls using cone-beam computed tomography with the ultimate goal of finding whether cleft lip and palate patients are more liable to nasopharyngeal airway obstruction.

Design: A retrospective analysis comparing bilateral cleft lip and palate, unilateral cleft lip and palate, and control subjects. Significance at P ≤ .

Acellular dermal matrix allograft: An effective adjunct to oronasal fistula repair in patients with cleft palate.

Context: Oronasal fistula (ONF) following cleft palate (CP) repair are a challenging problem associated with high recurrent rates. Acellular dermal matrix allograft is an available tissue substitute.

Aims: The aim of this study was to evaluate the effectiveness of acellular dermal matrix in the repair of ONF associated with CP that is recurrent or larger than 15 mm in any dimension.

Premaxillary characteristics in complete bilateral cleft lip and palate: A predictor for treatment outcome.

Objectives: The aim of the current study was to investigate how bilateral cleft lip and palate (BCLP) cases responded differently to presurgical orthopedics (PSO) and primary lip repair (LR) based on premaxillary characteristics. We suggest a clinically oriented descriptive classification for BCLP based on premaxillary characteristics.

Design And Setting: A retrospective longitudinal comparative study where available records of all non-syndromic patients with complete BCLP attending the Cleft Clinic, affiliated to the Oral and Maxillofacial Surgery department, Ain-Shams University, Cairo, Egypt were assessed.
