This paper describes a numerical study performed with the finite element method of novel dental implant system. A conventional Brånemark dental implant system was redesigned and a bio-inert stress barrier (elastomer) was interposed between the implant and the ceramic crown. The goal was to attenuate the loading of the bone surrounding the implant with high magnitude stresses. The new design was...
OBJECTIVES Bone loss around dental implants is generally measured by monitoring changes in marginal bone level using radiographs. After the first year of implantation, an implant should have <0.2 mm annual loss of marginal bone level to satisfy the criteria of success. However, the process of measuring marginal bone level on radiographs has a precision of 0.2 mm (or more) owing to variations in...
Background and aim: Neurosensory disorders after implant insertion are one of the main concerns in implant treatments. Neurosensory disorders can be driven by different factors including the contact of the implant with the nerve, pressure of edema, hematoma, scar, or dental injections. This study aimed at investigating the distance between the implant and the inferior alveolar nerve (IAN) and i...
conclusions consequently, this study shows promising results for il of single implants, and it can be considerable that treatment with microtextured surface implants is a predictable and appropriate method of treatment. background the immediate loading (il) protocol has gained increased popularity among surgeons in the last decade. objectives this study aimed to evaluate the clinical performanc...
objective: successful bonding of a dental implant to bone, which was referred to as osseointegration by branemark has been well documented. however, long-term prognosis of an implant depends on adequate maintenance and long-term care. an effective maintenance program is required to preserve the health of peri-implant tissues. several techniques have been suggested for this purpose but it is not...
The implant geometry provides a key role in the osseointegration process and is able to improve mechanical interaction primary stability into bone tissue. aim of present investigation was compare different profiles evaluate their influence on high-density polyurethane block. Methods: A total 100 implants were used 20 pcf density investigation, i.e., for each 5 groups (A, B, C, D, E), characteri...
The biological interaction between the jaw bones and dental implant is fundamental for the long-term success of dental implant placement. Nevertheless, the insufficient bone volume remains a major clinical problem, especially in case of immediate dental implant. Using a canine model, the present study proves the regenerative potential of adipose- derived stem cells (ADSCs) to repair peri-implan...
