Filter by:The aim of this randomized prospective clinical trial was to evaluate the outcome of bone block harvesting from the retromolar region using the Conventional and Piezosurgery Method. The study was planned on 19 patients (13F,6M) on 31 donor sites. In patients with bilateral bone harvesting, the donor site and the surgical method to be used were determined by the randomization protocol, while in patients with bone harvesting from a single site, the donor site was determined by considering parameters such as proximity to the operation site and distance to the inferior alveolar nerve. Clinical parameters such as operation time, pain, swelling, trismus, nerve damage were evaluated.
It is aimed to compare the bone changes and the amount of marginal bone loss after prosthetic loading around the immediately placed implants using the Socket Shield Technique with or without flap elevation.
An animal study and our pilot human study demonstrated that placing a smooth-surface titanium bone screw (TBS) over the buccal plate of an extraction socket resulted in less dimensional changes of the alveolar ridge along with no adverse effects. The purpose of this randomized clinical trial is to investigate the effectiveness of TBS application for ridge preservation in comparison to (1) unassisted/non-interventional socket healing and (2) alveolar ridge preservation (ARP) approach using allografts and a membrane.
The primary aims of this study are to compare, after 4 months, the clinical and histologic results of a combination demineralized/mineralized putty allograft vs. synthetic calcium phosphosilicate (CPS) putty alloplast graft utilization in socket preservation procedures. A regenerative tissue matrix membrane will be used to cover each graft lying below the flap.
The study was conducted on 20 immediate implant placement sites in the anterior maxillary region. In the study group, 10 implants were inserted using socket shield technique, while in control group, 10 implants were inserted using conventional immediate placement technique. All patients received immediate and 6 months post-operative CBCT to assess horizontal bone loss, vertical bone loss, and measurement of bone density. Implant stability quotients (ISQs) was measured immediately, 1st, 3rd and 6 months post-operatively.
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).
In this clinical study ridge splitting procedures are preformed using autogenous bone blocks. After a 3-month healing, at the time of dental implant placement bone core biopsy samples are harvested. The samples undergo micro-Ct and histomorphometric analysis.
This pilot multicentric randomized controlled clinical trial is aimed at evaluating the composition of the new-formed tissue into the dental socket after 6 months from tooth extraction and the application of a combination of xenograft bone granules and collagen membrane. Extraction sites will be either grafted with Dentsply Symbios Xenograft Granules and covered with Dentsply Symbios pre-hydrated Collagen Resorbable Membrane or grafted with Geistlich Bio-Oss Collagen and covered with Geistlich Bio-Gide membrane. Results will be compared to spontaneous socket healing.
According to previous scientific evidence lining on biological concept of bone regeneration into the maxillary sinus, an observational study was set up to record possible (hypothesized) difference in bone formation between different width of the maxillary sinus itself. Therefore, a multicenter study was set up that foresaw a surgical intervention of sinus lift with lateral approach, the 6 months healing phase, the implant insertion in two sites with the implant site preparation made by a trephine bur to retrieve a bone specimen for histomorphometric examination without any additive invasively for the patient.
The study evaluated the effect of local application of simvastatin around immediate implant on the amount of gap fill, ridge dimensional alterations and bone density in humans.
