Rehabilitation of edentulous patient using endosteal and subperiosteal implants: A case report

Introduction: Endosteal implants may be insufficient in treating complete edentulism in severe bone loss, such as advanced bone resorption, trauma, infection, intraoral pathologies, and traumatic tooth extractions. With the developing technology, in cases where bone quality and quantity are inadequate, treatment with custom-made subperiosteal implants also emerges as an alternative. Case: This case report examined the procedural steps and the six-month post-operative period while evaluating our edentulous patient who rehabilitated using endosteal and custom-made subperiosteal implants. Results: No resorption or mobility of the implants was detected in the 6th-month post-operative control of our complete edentulous case, which was rehabilitated using traditionally used intra-bone implants in the maxilla and subperiosteal implants in the mandible. Conclusion: One of the essential advantages of the subperiosteal implant system is that it provides fixed prosthetic treatment, especially in jaws with advanced bone atrophy. Correct case selection and appropriate surgical and prosthetic treatment will increase success. Keywords: Dental implantation; Endosteal; Mouth rehabilitation; Subperiosteal

A comparative study of marginal fit of copings prepared with various techniques on different implant abutments

This study evaluated fabrication techniques of recently introduced all-ceramic copings' marginal adaptation on two different implant abutments with different finish lines. Five different copings were prepared (Casted chrome-cobalt metal coping, Zirkonzahn, Cercon, In Ceram Alumina and IPS e.max Press) on two cementable implant abutments with two marginal designs. Ten samples for each coping group were prepared (totally 100 samples). Copings were cemented to implant abutments and marginal gap measurements were done from 24 points with stereomicroscope and the datas were analyzed by the Kruskal-Wallis test before cementation. Cercon copings showed the lowest marginal fit scores and metal copings showed the highest scores. After cementation, all marginal gap values have been increased. All marginal gap values obtained from crown copings can be considered in clinically acceptable limits (<120 mu m) except metal copings after cementation on abutment with 135 degrees shoulder group (123 mu m)

VISUAL AND INSTRUMENTAL EVALUATION OF COLOR MATCH ABILITY OF 2 SHADE GUIDES ON A CERAMIC SYSTEM

Statement of problem. There is limited information on the visual and instrumental evaluation of color match between a natural tooth and a ceramic crown

The Effect of Mouthrinses on Color Stability of the Restorative Materials

Purpose:The aim of this study was to investigate the effect of 6 types with different chemical structure mouth rinses on the color stability of esthetic restorative materials

Stainability of different ceramic materials against mouth rinses and effect of polishing after staining.

Statement of problem. Mouth rinses are known to stain tooth surfaces. However, their staining effect on different ceramics after prolonged use and the effect of polishing after staining are still unclear

Comparing the precision of reproducibility of computer-aided occlusal design to conventional methods

Purpose: Reconstruction of patients' dental occlusion should be performed to fulfill esthetic and functional demands. These applied restorations should be in harmony with the existing occlusion and should not have any negative effects on intraoral dynamics. The aim of this clinical study is to compare the accuracy of the occlusal design shaped by conventional Wax Up methods and computer-aided design (CAD) regarding their similarity to the natural tooth morphology

Comparative Evaluation of the Effects of Implant Position, Impression Material, and Tray Type on Implant Impression Accuracy

Purpose: To evaluate the effect of implant position, impression, and tray material on the accuracy of implant impressions of edentulous arches with multiple implants
