Clinical Evaluation Of Dental Implants Stability Placed In Healed Bony Sites Following Over-drilling Compared To Conventional-Drilling Protocol
20 patients were selected requiring implant placement and divided randomly into two groups (10 in each group) - for the study group, starter drill is used to locate the point of insertion as planned then pilot drill is also used to the full desired working length after that all other sequential drills are used at a low speed (50-70 rpm) without irrigation . - In the study group: implant will be inserted in the low speed osteotomy site. • In the co...

The aim of this study is to evaluate the influence of superstructure material on crestal bone resorption and esthetic outcome of dental implants in patients with single missing tooth in the aesthetic zone.
Crestal bone and soft tissue stability around implants is an important issue in implant dentistry. Initial vertical mucosal tissue thickness was shown to be one of the factors having impact on bone stability. However, there is lack of data in the literature regarding the relationship between mucosal thickness and marginal bone loss around implants. Berglundh and Lindhe in an animal study reported that thin mucosal tissue causes significantly more crestal bone resorption around ...
Implants have become the preferred method of single tooth replacement these days, patients receiving implant treatments not only expect restoration of masticatory function, they also expect that the prostheses will be esthetically pleasing, easy to clean, and permanent. To maintain long-term implant stability, it is important to minimize bone loss around the implant, as well as the soft tissue atrophy that accompanies it.
This prospective, randomized study will evaluate the performance of the Osseotite Certain Prevail implant when compared to that of the non-lateralized version of the implant. Study (null) hypothesis: the crestal bone changes that take place after placement and loading of the Osseotite lateralized implants will be the same as for a similar but non-lateralized Osseotite Certain implant.
The aim of this observational study is the evaluation of marginal bone remodeling after surgical implant placement, correlating the gingival thickness with the bone resorption rate.
This prospective, randomized study evaluates the performance and crestal bone changes difference between the Osseotite Certain Prevail vs the non-lateralized design of the implant. Study (null) hypothesis: the crestal bone changes that take place after placement and loading of the Osseotite lateralized implants will be the same as for similar but non-lateralized Osseotite Certain implants.
Systemically healthy volunteers with no active periodontal disease are recruited from referrals to the Dept. of Preventive Dentistry, Periodontology and Biology of Implants, Aristotle Univ of Thessaloniki for implant therapy. After signing a consent form, participants will be randomized into two treatment groups. Group-A (NA=10) will receive crestal placement of implants following a two-stage protocol in combination with a biocomplex comprising autologous alveolar bone marrow m...
The purpose of this study is to assess the change of crestal bone level at the Titanium Zirconium (TiZr) compared to Titanium (grade IV) implant between surgery and 6, 12, 24, and 36 month post surgery.
Changes in the marginal bone level surrounding the implant are the frequently used parameters in assessing the short- and long-term success. Multiple biological and biomechanical factors have been reported to adversely affect marginal bone level. Recently, initial vertical mucosal tissue thickness has also been reported to have an impact on bone stability.The hypothesis of present study is that soft tissue thickness on implant placement has no positive impact of crestal bone re...
A successful implant therapy require appropriate hard and soft tissue, perfect implant position, appropriate alveolar ridge architecture and integration of the implant. after tooth extraction bone resorption takes place and affect the quantity and quality of the bone resulting in inadequate bone volume for implant placement and future prosthetic restoration and impair the esthetic, so insertion of implant immediately following tooth extraction reduce bone loss and enhance esthe...
multi center study with randomized controlled trial design, split mouth
Hypothesis There is no difference in the incidence of pin tract infection and pin loosening in case of lower extremity external fixators when self-drilling schanz pins are used with or without pre-drilling. Primary Objective The primary objective is to determine whether pre-drilling holes for external fixation pin insertion is superior to not pre-drilling holes for external fixation pin insertion in regards to the incidence of pin tract infection and pin loosenin...
Using growth factors obtained from patient's venous blood mixed with particulate autogenous bone the study compares bone gain by implant with gold standards in sinus Lift procedures for future implant insertion.
Using bone ring grafts with simultaneous implant placement after three-dimensional augmentation of severely defective bone ridges using computer-guided surgical templates. The study compares accuracy effectiveness by mimics software
Aim: The aim of this study to Assess the healing process of the immediate implant loading with two different provisional techniques (direct and indirect). Materials and methods: 20 implant in the aesthetic zone either in the incisor or in the canine area and excluding the lateral location and then immediate loading is achieved for the 20 implants (10 for direct and 10 for indirect method) Clinical Aspect :color change , healing and bone resorption Esthetic assessment an...
Bone quality is one of the major factors influencing the dental implant survival rate. Bone quality is believed to have effects on initial implant stability and success of osseointegration. Different implant designs and surgical protocols were developed for improving the survival rate in different bone quality. Although bone quality can be partly diagnosed by radiographic images, lots of experienced surgeons also evaluate bone quality with tactile sensation when they drill the ...
The purpose of this clinical and radiographic study will be to determine what influence on marginal bone loss has the thickness of soft tissues and the height of the prosthetic abutment and eventually determine which of the two factors is the most important.This research was designed as a multicentre cohort observational study. Eight clinical centers will treat patients through the placement of a single dental implant. The implants will be prosthetically loaded about 3 months a...
Based on manufacturer testing, no major difference in drilling condition is expected in this study compared to the drilling conditions previously established. However clinical testing is needed to establish optimal drilling conditions to be used for further development in both unaffected and affected parts of the nail. The aim of this study is to determine the optimal drilling condition that could be used in future studies of this device in combination with topical treatment f...
Implant placement may trigger bone trauma, which might result in 3-dimensional bone changes. While the process of peri-implant disease is not well understood, implant position within the bony structure might play a role. However, there is no data available on this regard.

The purpose of this study is to determine the survival rate, marginal bone resorption, soft tissue health and maintenance of the NobelActive Internal and External implants and to make comparisons with the NobelReplace Tapered Groovy implant placed in healed sites.
The subchondral bone, formed by the subchondral bone plate and the subarticular spongiosa, plays a key role in supporting the articular cartilage. Marrow stimulation techniques such as subchondral drilling are clinically important treatment options for symptomatic small cartilage defects. However, The heat generated from the metal-bone interface during drilling due to the friction can cause thermal osteonecrosis. , recent clinical evidence suggests that they may induce alterati...
