introduction: introduction: few studies have investigated the distribution of stress around implants. in this study the distribution of stress in bones around implants was investigated in five overdenture (od) treatment designs including od-1, od-2, od-3, od-4 and od-5. materials and methods: the catia modeling software was used in order to simulate the tooth/implant model and bone. first, the ...

background and aims . peri-implantitis is a chronic progressive marginal infection which is defined as an inflammato-ry reaction affecting the tissues surrounding osseointegrated dental implants resulting in loss of supporting bone. microflora of patients with implants who are edentulous mainly consists of gram positive facultative cocci and non motile rods. pre-dominantly, streptococcus sangui...

Objective Overdenture therapy is an important option for implant rehabilitation. However, numerous reports suggest that mechanical/technical complications and failures can limit therapeutic success. The goal of this report to illustrate a digital approach design construction robust overdenture with high-esthetic value. Materials methods Beginning new denture establish esthetic parameters, 3D mo...

This preliminary in vitro study evaluated the simulated retention force of O-rings used for mini-implant overdenture treatment and the effect of mechanical fatigue corresponding to 6 months of wear. A mandibular overdenture analog device was attached to two mini-implants and underwent a tensile strength test before and after the application of insertion-removal and simulated masticatory cycles....

conclusion of the asymptomatic patients investigated, 58% showed focal enhanced periprosthetic glucose metabolism. this finding should be taken into consideration as a more probable unspecific metabolic pattern for correct interpretation of 18f-fdg-pet studies in patients with suspected septic loosening of the hip prosthesis. results fourteen hip prostheses in 12 patients were visually analyzed...

great prosthesis for reinforcement of visceral sac is a guranteed operation for unilateral or bilateral inguinal hernias in otil patients or recurrent cases. the greatest use of this technique is in the patients who are at specially high risk for recurrence. we successfully accomplished this technique in 70 cases in our hospital while the patients were countiniously under our close inspection f...

Resorpsi residual ridge yang parah sering kali menyebabkan kegagalan perawatan gigi tiruan lengkap akibat rendahnya stabilitas dan retensi. Terdapat beberapa cara untuk dapat meningkatkan ridge, antara lain dengan modifikasi teknik mencetak menggunakan sisa asli sebagai penyangga overdenture. Teknik neutral zone tiruan. ini memungkinkan penyusunan anasir gigipada daerah keseimbangan otot. Pengg...
