Filter by:To assess the accuracy of the computer assessed guides in horizontal bone augmentation achieved at posterior mandible using guided modified ridge splitting technique versus free hand modified ridge splitting technique
To evaluate the quantity and quality of bone generated, radiographically and histomorphometrically, after guided bone regeneration (GBR) using a membrane of 3D printed custom made (PMMA) and subsequent stability of delayed implant placement.
Sixteen healthy patients selected from the Outpatient Clinic of the Department of Oral Medicine, Periodontology, Diagnosis and Oral Radiology, Faculty of Dentistry, Mansoura University for the replacement of missing single maxillary anterior or premolar tooth (in the esthetic zone) by dental implant. Patients were selected according to the following criteria: 1) Patients older than 18 years. 2) Good general health, with no systemic diseases that might contraindicate receiving a dental implant. 3) Every patient should have at least one missing tooth in the maxillary anterior premolar area and subsequently scheduled for implant supported prosthesis. 4) The tooth has been extracted from at least 3 months. 5) Insufficient horizontal bone (class III according to Len Tolstunov classification. 6) Good oral hygiene. Patients were classified into two groups: Group (I) (study group): eight patients with missing anterior or premolar tooth with insufficient horizontal (bucco/labio palatal) bone width were treated with dental implants and Bond Apatite (AugmaBio, United States of America) as a bone graft material to fill the defect. Group (II) (positive control group): eight patients with missing anterior or premolar tooth with insufficient horizontal (bucco/labio palatal) bone width were treated with dental implants and Bio-Oss (Bio-Oss, GeistlichPharmaAG, Wolhusen, Switzerland) as a bone graft material to fill the defect and pericardium resorbable membrane. Patients were evaluated with the following clinical and radiological parameters presurgical and 12 months after operation: A) Clinical evaluation: The following parameters were evaluated: 1. Modified plaque index: This is fundamentally based on the visual detection of plaque, it ascertains the thickness of plaque along the gingival margin, namely the desirability of distinguishing clearly between severity and the location of soft debris aggregates. 2. Modified gingival index: It is a method to assess the severity of gingivitis based on gingival color, contour, presence of bleeding, stippling and crevicular fluid flow. It is completely noninvasive method (only visual). 3. Probing depth: Peri-implant pocket depth was measured using plastic implant probe (contrast PA probe # CPNG22, Helmut Zepf Medizintechnik Gmbh®) after final restoration was inserted. B) Radiographic evaluation: Bone width was assessed using CBCT 12 months after implant insertion. Bone width measurements were made on tomographic slices perpendicular to the longitudinal axis of the alveolar crest; 2 mm from the alveolar crest.
this study compares 2 techniques in guided bone regeneration for horizontal ridge augmentation in aesthetic zone
This study aimed to evaluate the efficacy of 1% metformin gel mixed with PRF, in horizontal ridge augmentation with the split-crest technique, for implant placement.
this study aims to evaluate horizontal bone augmentation achieved at the anterior maxilla using computer-guided cortical shell bone technique and accuracy of fixation of the bone shell away from the atrophic ridge by a calculated distance which is always a challenging step for inexperienced surgeons to fix a cortical shell at the ideal position in the conventional protocol it was never guided to be precisely fixed at the proper position and angulation the problem is if it fixed with insufficient distance with proposed volume loss leads to totally insufficient volume gain for future implant placement also to evaluate the efficacy of the CAD/CAM surgical guide during chin harvesting procedures in reducing the risk of anatomical structure damage and patient morbidity with more accuracy compared with the standard technique. this trial versus free hand conventional cortical shell bone technique both harvested from symphysis area (chin).
Cases with horizontal ridge deficiency less than what is possible for ridge splitting were recruited and the buccal cortex was totally separated and lateralized at the desired distance for augmentation
The purpose of this study is to compare two bone graft wound healing techniques; an open wound healing approach versus the standard closed wound healing approach.
A prospective observational clinical study guided by the guidelines of Strengthening the Reporting of Observational Studies in Epidemiology (STORBE) in 2014, that conducted to assess amount of ridge expansion obtained by using Dansah burs with simultaneous implant placement.
The primary aim of this study is to clinically, radiographically and histologically evaluate the lateral bone augmentation of the soft porcine cortical lamina (OsteoBiol®) using equine-derived bone particles (OsteoBiol®)
