The aim of this study was to evaluate bone resorption quantitatively during the healing period subsequent to ridge augmentation.

Coupling of bone resorption and formation.

Preceding bone resorption is a prerequisite for the initiation of subsequent bone formation during adulthood and the quantity as well as the quality of bone is maintained by which newly formed bone by osteoblasts replaces precisely the amount removed by osteoclastic bone resorption at the same level. This process is namely " bone remodeling " and the rely of bone formation in response to resorption is termed " coupling " . Importantly, bone formation is induced by osteoclastic bone resorption or the presenc...

The influence of crown-to-implant ratio on marginal bone levels around splinted short dental implants: A radiological and clincial short term analysis.

Implant-Abutment Connections: A Review of Biologic Consequences and Peri-implantitis Implications.

Clinicians very often have seen marginal bone loss around dental implants at the crest level early on after implant placement and uncovering. Early clinical publications had suggested that this bone loss occurred during the first year of loading. Thus, numerous attempts have been made to minimize or eliminate such bone loss. However, the timing and reason for this bone loss are not always apparent. The objective of this study was to review the evidence regarding marginal bone loss around dental implants fro...

Peri-implant Crestal Bone Changes Around Zirconia Implants in Periodontally Healthy and Compromised Patients.

No consensus regarding the efficacy of zirconia implants in maintaining peri-implant hard and soft tissue health has yet been obtained. The aim of this retrospective follow-up study was to gain knowledge about peri-implant bone behavior and about implant survival and success after treatment with zirconia dental implants in patients with normal and compromised soft and hard tissue conditions.

The role of osteoclastic bone resorption on bone remodeling.

Bone remodeling consists of bone resorbing cycle and bone forming cycle to maintain bone volume and calcium homeostasis thought life. The main cells involves in bone remodeling are osteoclasts and osteoblasts. Bone resorption and bone formation are tightly coupled during bone remodeling, an imbalance of these two processes leads to either increased or decreased bone mass. Osteoclasts are multinucleated cells responsible for physiological and pathological bone resorption and thereby play an essential role in...

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.

Improved dental implant drill durability and performance using heat and wear resistant protective coatings.

Dental implant drilling procedure is an essential step for implant surgery and frictional heat appeared in bone during drilling is a key factor affecting the success of an implant. The aim of this study is to increase the dental implant drill lifetime and performance using heat- and wear-resistant protective coatings hence to decrease the alveolar bone temperature caused by the dental implant drilling procedure. Commercially obtained stainless steel drills were coated with titanium aluminum nitride, diamond...

Incidence and Management of Fractured Dental Implants: Case Reports.

The fracture of dental implants is a rare occurrence in clinical settings. Possible causes of implant fracture include design or production flaws, overloaded occlusion force, implant location, metal fatigue, and bone resorption around the implant. This study reports on the successful removal and reimplantation of fractured implants.

Impaired bone formation in ovariectomized mice reduces implant integration as indicated by longitudinal in vivo micro-computed tomography.

Although osteoporotic bone, with low bone mass and deteriorated bone architecture, provides a less favorable mechanical environment than healthy bone for implant fixation, there is no general agreement on the impact of osteoporosis on peri-implant bone (re)modeling, which is ultimately responsible for the long term stability of the bone-implant system. Here, we inserted an implant in a mouse model mimicking estrogen deficiency-induced bone loss and we monitored with longitudinal in vivo micro-computed tomog...

Mandibular implant-retained overdenture relining procedure with an attachment system: A step-by-step demonstration of the technique.

Because of continuous alveolar bone resorption, implant-retained overdentures need to be relined. The purpose of this study was to describe a method for relining an implant-retained overdenture.

Optimal selection of dental implant for different bone conditions based on the mechanical response.

Bone quality varies from one patient to another extensively. Young's modulus may deviate up to 40% of normal bone quality, which results into alteration of bone stiffness immensely. The prime goal of this study is to design the optimum dental implant considering the mechanical response at bone implant interfaces for a patient with specific bone quality.

Influence of hip prosthesis size and its coating area on bone remodelling.

We developed a numerical model to describe the bone remodelling process in periprosthetic bone tissues and validated it by means of dual energy X-ray absorptiometry methods (DEXA) with different types of hip implants. In this study we applied the numerical model to investigate the influence of implant size and of the size of the porous coated area on bone remodelling in a periprosthetic human femur in an effort to define properties of implants which would reduce bone remodelling after total hip arthroplasty...
