Simplifying Zygomatic Implant Site Preparation Using Ultrasonic Navigation: A Technical Note.

Zygomatic implant site preparation could be considered a challenging procedure because of the use of a very long twist drill that could sometimes be difficult to control due to the need for drilling the malar bone on an oblique surface. Ultrasound was recently suggested to achieve better control, but the specific long tips required are not readily available, and the elongated tip also tends to reduce the efficacy. This technical note describes a proposal of a novel computer-aided technique to simplify the p...

A Review of the Impact of Implant Biomaterials on Osteocytes.

In lamellar bone, a network of highly oriented interconnected osteocytes is organized in concentric layers. Through their cellular processes contained within canaliculi, osteocytes are highly mechanosensitive and locally modulate bone remodeling. We review the recent developments demonstrating the significance of the osteocyte lacuno-canalicular network in bone maintenance around implant biomaterials. Drilling during implant site preparation triggers osteocyte apoptosis, the magnitude of which correlates wi...

Decoronation followed by dental implants placement: fundamentals, applications and explanations.

Dental arches areas with teeth presenting dentoalveolar ankylosis and replacement root resorption can be considered as presenting normal bone, in full physiological remodeling process; and osseointegrated implants can be successfully placed. Bone remodeling will promote osseointegration, regardless of presenting ankylosis and/or replacement root resorption. After 1 to 10 years, all dental tissues will have been replaced by bone. The site, angulation and ideal positioning in the space to place the implant sh...

Clinical Outcome After 8 to 10 Years of Immediately Restored Single Implants Placed in Extraction Sockets and Healed Ridges.

Implant/Abutment Biomechanics and Material Selection for Predictable Results.

Change in crestal bone height and volume around endosseous dental implants is a complex issue involving interactions among many variables such as surgical approach, patient health, volume of hard and soft tissues, and implant configuration. Establishing and maintaining a soft-tissue seal around transmucosal abutments on bone-level implants or on the collar of one-stage tissue-level implants is paramount to maintaining crestal bone height, and failing to do so will result in apical migration of the soft tiss...

Are Intraoral Radiographs Accurate in Determining the Peri-implant Marginal Bone Level?

The primary objective of this study was to assess the accuracy of periapical radiographs in determining the peri-implant marginal bone level. The accuracy of the linear measurements on radiographs was considered as the absolute difference between the true, intraoperative or surgical marginal bone level measurements (direct bone measurements during surgical procedures) and the radiographic measured distances. The secondary aims were to identify the variables influencing the radiographic evaluation (arch: man...

Allogeneic Bone Block Volume Preservation in Ridge Augmentation for Implants.

Allogeneic bone blocks are commonly used for bone augmentation in implant dentistry. Allogeneic bone blocks have the advantage of containing growth factors and the original human scaffold. A major disadvantage is the risk of substantial graft volume decrease due to resorption. The purpose of this study was to evaluate whether corticocancellous allogeneic bone blocks can predictably maintain graft volume to allow implant placement and esthetic restoration. A total of 141 allogeneic bone blocks were placed in...

Biomechanics of Immediate Postextraction Implant Osseointegration.

The aim of this study was to gain insights into the biology and mechanics of immediate postextraction implant osseointegration. To mimic clinical practice, murine first molar extraction was followed by osteotomy site preparation, specifically in the palatal root socket. The osteotomy was positioned such that it removed periodontal ligament (PDL) only on the palatal aspect of the socket, leaving the buccal aspect undisturbed. This strategy created 2 distinct peri-implant environments: on the palatal aspect, ...

Correlation between the thickness of the crestal and buccolingual cortical bone at varying depths and implant stability quotients.

Resonance frequency analysis (RFA) is clinically used in dentistry to access the stiffness of dental implants in surrounding bone. However, the clear advantages and disadvantages of this method are still inconclusive. The aim of this study was to investigate and compare implant stability quotient (ISQ) values obtained from RFA with parameters obtained from a cone beam computed tomography (CBCT) scan of the same region.
