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...

After tooth extraction, host bone resorption and atrophy of alveolar ridge may be observed. Bone resorption occurs specially in incisors and premolar area of jaw in region of thin buccal bone that may lead to change in contour. Total clinical bone loss height approximately 2-5 mm at first 6 months may be observed in vertical dimension , after 12 months alveolar ridge may lose up to 50 % of its width.
- Vitamin D considers as the most potent effect on calcium level in blood it was found that vitamin D target mainly bone tissue intestine and kidney for calcium absorption In bone, vitamin D stimulates mainly the activity of osteoclasts osteoblast activity on the other hand it increases the production of extracellular matrix proteins by different osteoblastic activity. Vitamin D also increase intestinal calcium absorption and regulate synthesis and secretion of parathyroid horm...
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 ...
The amount of hard tissue resorption following tooth extraction involves prosthetically driven implant placement; therefore, the development of ridge preservation techniques that result in less alveolar bone loss is of great interest, Alveolar ridge preservation are indicated to decrease the loss of ridge volume that follows tooth extraction.However, they do not prevent bone resorption because, depending on the technique.The protocol of placing implants immediately upon tooth e...
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.
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...
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.
The aim of the study was to determine whether implant length and the crown-to-implant (C/I) ratio influence implant stability and the loss of the surrounding marginal bone, and whether short implants can be used instead of sinus augmentation procedures.
In implant dentistry, platform switching is a method used to preserve alveolar bone levels around dental implants. The concept refers to using an implant with slopped shoulder neck of narrower diameter on implants of wider diameter, rather than placing abutments of similar diameter, referred to as platform matching.The aim of the study is to compare the effect of bone-level implants versus the conventional implant on oral soft tissues.
comparing the drilling technique of using densah burs osseo densification drills in posterior maxilla with the normal surgical kit drilling
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.
This study aims to evaluate the levels of cytokines, chemokines and growth factors in peri-implant sulcular fluid (PISF) during healing and osseointegration at osteotomy sites prepared either with piezosurgery (PS) or drills (D). Fourteen patients having bilateral partial edentulism in the posterior maxilla were enrolled and 38 osteotomies were prepared. Implants were placed with one-stage surgery. Insertion torque, early healing index, probing depth and modified gingival and p...
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...
Immediate implant placement has a success rate from 94-100 % . After tooth extraction there is a loss in the horizontal and vertical dimension by about 3-6 mm and 1-2 mm respectively and alveolar crest resorption of about 44% especially through 6 months after extraction. After immediate implant placement there is usually a void between the implant and the socket walls which is called jumping distance or gap which may heal spontaneously or need bone graft to bridge the space. I...
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
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.
The objective of this human randomized, double blind, placebo-control (RDBPC) study is to evaluate the efficacy of a 0.2% chlorhexidine (CHX) gel on reducing bacterial load and peri-implant inflammation at implant-abutment interface during the early healing stage.Thirty-six healthy patients (mean age 52,28 years; range 29-75 years) without a significant past medical anamnesis, all non-smokers, will be recruited as candidates for single implant placement and prosthetic rehabilit...
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...
