statement of the problem when root perforation occurs in the middle third of the root, considerable canal length that would normally be available for post placement must be filled by the repair material, which necessitates placement of a considerably shorter post, leading to poor retention. purpose the aim of this study was to compare retention of titanium parapost luted with mta and four diffe...

Infection is a potentially disastrous complication of total knee replacement (TKR). Retention of the prosthesis has been associated with high rates of persistent infection. Our study shows that in selected situations, arthroscopic debridement may allow retention of the prosthesis and eradication of the infection. However, the prosthesis must be stable, the surgical technique must be meticulous ...

Maxillary defects are created by surgical treatment of benign or malignant neoplasms, congenital malformation and by trauma. The size and location of the defects in ̄uence the degree of impairment and dif®culty in prosthetic rehabilitation. Lack of support, retention, and stability are common prosthodontic treatment problems for patients who have had a maxillectomy. A prosthesis used to close a ...

Large maxillofacial defects from malignant tumor treatment are rarely rehabilitated by surgical reconstruction alone. Ameloblastic carcinoma, a rare aggressive odontogenic malignant tumor, requires wide surgical excision to gain a tumor-free margin. In the post-surgical defect, prosthetic rehabilitation is the treatment of choice to restore function and esthetics. Moreover, an intra-oral prosth...

Ceramic post-and-core systems offer biocompatibility, aesthetics, reinforcement of the remnant root, and prosthesis retention. Aesthetic posts-and-cores contribute to the optical properties of the overlying restorations when metal-free crowns are used. This article illustrates the use of these materials to provide strength and aesthetics during the restoration of endodontically treated teeth. T...

ment depends on the successful integration of the prosthesis with the patient’s oral functions plus psychological acceptance of the dentures by the patient. These parameters require that patients perceive their dentures as stationary or well retained during function, and that the prostheses and their effects on the face meet the esthetic and psychodynamic requirements of the patient. In this ch...

Conventional complete denture is the traditional treatment plan for the completely edentulous patient. Unfortunately, this treatment option has several complications, especially for the lower denture. The advance of a dental implant with attachment systems resolves many of these issues, particularly that related to the denture retention and stability. A wide variety of commercially available at...

BACKGROUND Implants that can be used in the prosthetic rehabilitation of full and partial edentulous patients are now frequently used due to advances in dentistry. Despite advanced methods of applications, failures and complications can still be seen. The aim of our study was to evaluate clinical prosthetic values and complications that occurred during 4-year follow-up in implant-supported rest...

Utilizing natural teeth to enhance support for prosthesis is not new in prosthodontics. Few teeth can be conserved in compromised edentulous ridge patients and be used to provide support to the prosthesis. The use of stud attachments allows the ability to the clinician to improve the retention of the prosthesis, thus allowing the patient to experience better comfort.
