background: fracture load of implant-supported restorations is an important factor in clinical success. this study evaluated the effect of two techniques for screw access hole preparation on the fracture load of cement-screw retained implant-supported zirconia-based crowns. methods: thirty similar cement-screw retained implant-supported zirconia-based maxillary central incisor crowns were evalu...

Prosthodontic rehabilitation of a patient with an atrophic edentulous mandible presents a significant challenge in restoring esthetics and function. The purpose of this clinical report is to describe fracture of an atrophic edentulous mandible opposing maxillary natural dentition in association with endosseous dental implants. The patient received two wide-diameter implants in the anterior mand...

During an assessment of dental implant design effectiveness, most the data are acquired from clinical or animal studies performed by researchers and clinicians. In order to represent scientific significance, those have be properly designed, focusing on a precisely chosen aspect with inclusion exclusion criteria. The last these, especially, can create major limitations for collection. reliable, ...

The aim of this study was to attempt to determine the minimum effective regimen of Amoxicillin antibiotic prophylaxis for dental implant surgery. One hundred patients were randomly allocated to four different antibiotic prophylactic treatment groups. At second stage surgery only 2 implants failed in the non-antibiotic group. No statistically significant differences were found in the 4 groups, p...

If dental implantology is an increasingly successful treatment modality, why should we still need to understand the mechanisms of peri-implant bone healing? Are there differences in cortical and trabecular healing? What does "poor quality" bone mean? What stages of healing are most important? How do calcium phosphate-coated implants accelerate healing? What is the mechanism of bone bonding? Whi...

discussion this segmental ridge-split procedure with gradual bone expansion provides a quicker method wherein an atrophic ridge can be predictably expanded and eliminating the need for a second surgical site. this technique also shows that immediate implantation in split ridge of mandible can be performed. introduction narrow alveolar ridges especially in posterior mandibular remains a serious ...

The use of uncemented titanium endosseous implants for restorative dentistry and orthopaedic surgery has been the standard of care for several decades. Endosseous implantation using uncemented titanium prostheses is commonly performed in trabecular bone sites such as the jaws, vertebrae and ileum. Still, the mechanisms involved in this fascinating and unique interaction between a living tissue ...

background. improving the implantation conditions in order to reduce the failure is always desirable for researchers. the aim of this study was to compare two different types of dental implant materials from biomechnical viewpoint in order to introduce a novel simulation method to select suitable materials for dental implants. methods. in this research, drilling process was performed in the cor...
