To compare the technique of high speed drilling with irrigation and low speed drilling without irrigation in order to evaluate the success rate and peri-implant bone loss at 12 months of follow-up.
The subcrestal placement of implant platform has been considered a key factor in the preservation of crestal bone, but the influence of implant placement depth on bone remodeling combined with peri-implantitis is not fully understood. The aim of this study was to assess the effect of the crestal or subcrestal placement of implants on peri-implant bone defects of ligature-induced peri-implantitis in dogs.
This study evaluated implant outcome in patients with Down syndrome (DSPs) and provides clinical guidelines to maximize treatment outcome. A total of 57 implants were placed in eight DSPs. During follow-up, implant survival was recorded and crestal bone level was evaluated when possible. After a mean follow-up time of 5 years, six patients with 45 implants were evaluated and an implant survival rate of 84.4% was recorded. A mean crestal bone loss of 1.7 mm (SD 0.9) was measured in three patients around 20 i...
The aim of this study was to evaluate bone resorption quantitatively during the healing period subsequent to ridge augmentation.
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 amount of marginal bone resorption around dental implants is considered to have a significant impact on implant stability as well as implant survival rates.
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...
Recent systematic reviews point to the scarcity of single implants followed up longer than 5 years, and the incidence of biologic/technical complications is underreported. This prospective follow-up study documents 8- to 10-year clinical outcomes of immediately restored single implants in extraction sockets (immediate implant treatment [IIT]) and healed bone (conventional implant treatment [CIT]). Patients received a single, chemically modified, moderately rough titanium implant and a provisional crown on t...
The aim of this study was to evaluate the evidence of a correlation between the stability of dental implants placed by piezosurgery, compared with implants placed by conventional drilling. An electronic search in MEDLINE, SCOPUS and the Cochrane Library was undertaken until August 2016 and was supplemented by manual searches and by unpublished studies at OpenGray. Only randomized controlled clinical trials that reported implant site preparation with piezosurgery and with conventional drilling were considere...
The aim of this study was to evaluate osseointegration and crestal bone height in implants with a triangular cervical design in comparison with a standard rounded cervical design. The control group consisted of 24 implants with a standard cervical design, and the test group of 24 implants with a triangular cervical design. The implants were inserted in healed bone in six American Foxhounds. Crestal bone height and tissue thickness in the cervical portion were measured after 12 weeks healing. Data analysis f...
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.
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...
Allogeneic bone blocks are commonly used for bone augmentation in implant dentistry. Allogeneic bone blocks have the advantage of containing growth factors and the original human scaffold. A major disadvantage is the risk of substantial graft volume decrease due to resorption. The purpose of this study was to evaluate whether corticocancellous allogeneic bone blocks can predictably maintain graft volume to allow implant placement and esthetic restoration. A total of 141 allogeneic bone blocks were placed in...
The aim of this study was to gain insights into the biology and mechanics of immediate postextraction implant osseointegration. To mimic clinical practice, murine first molar extraction was followed by osteotomy site preparation, specifically in the palatal root socket. The osteotomy was positioned such that it removed periodontal ligament (PDL) only on the palatal aspect of the socket, leaving the buccal aspect undisturbed. This strategy created 2 distinct peri-implant environments: on the palatal aspect, ...
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.
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...
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.
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...
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.
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.
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...
The Encode protocol (Biomet 3i, Palm Beach Gardens, Fla) has been proposed as a simplified implant restoration protocol.
The success of implant-based treatment is dependent on the correct restorative position of dental implants in the oral cavity. Often, the final prostheses require dental implants to be placed at sites with inadequate native hard and soft tissue. Bone augmentation procedures and materials have been extensively studied in the literature and various techniques have been developed over time to obtain adequate hard tissue at proposed implant sites. In the recent past, few publications have also studied soft tiss...
