The objective of the study is to evaluate histomorphometrically the healing at implants installed with standard or very low insertion torque values.
Very high insertion torque values have been recommended when immediate loading is applied to implants.1 However, it has been shown that similar clinical outcomes may be achieved even with insertion torque values ≤15 Ncm when implants are splinted together. Due to the contradictory outcomes on the influence of the torque on osseointegration and a lack of histological data in humans, there is a need of more evidences that may support the clinicians in the decision making when an unintentional low insertion torque occur at implants during the daily practice. So the aim of the study i evaluate histomorphometrically the healing at implants installed in Twelve volunteer patients that will be recruited. Two screw-shaped titanium devices will be installed in the distal segments of the mandible using insertion torque values of either <10 Ncm or ~30 Ncm. The implants were left to heal in a non-submerged fashion. After 8 weeks, biopsies will be retrieved and ground sections will be prepared for histological evaluation.

Implant Survival in the Partially Edentulous Jaw- 30 Years of Experience. Part III: A Retro-Prospective Multivariate Regression Analysis on Overall Implant Failures in 2,915 Consecutively Treated Arches.
To report implant failure rates in a large group of partially edentulous patients over a long-term period and to analyze possible associations between available clinical variables and implant failure.
To further report and analyze data on the prevalence of implant failures related to age at surgery in partially edentulous jaws.
The aim of this study was to evaluate the accuracy of computer-guided flapless implant (CGFI) surgery in edentulous jaws with fresh extraction sockets and compare it to CGFI in fully edentulous jaws.
Degradation or wasting of the PERIODONTIUM tissues that may involve the gum (GINGIVA), the alveolar bone (ALVEOLAR PROCESS), the DENTAL CEMENTUM, or the PERIODONTAL LIGAMENT.
The total absence of teeth from either the mandible or the maxilla, but not both. Total absence of teeth from both is MOUTH, EDENTULOUS. Partial absence of teeth in either is JAW, EDENTULOUS, PARTIALLY.
The fibrous CONNECTIVE TISSUE surrounding the TOOTH ROOT, separating it from and attaching it to the alveolar bone (ALVEOLAR PROCESS).
The use of a treatment material (tissue conditioner) to re-establish tone and health to irritated oral soft tissue, usually applied to the edentulous alveolar ridge.
Resorption or wasting of the tooth-supporting bone (ALVEOLAR PROCESS) in the MAXILLA or MANDIBLE.
