Prosthodontic Rehabilitation using Maxillary Fixed Dental Prosthesis with Tenon and Mortise Stress Breaker and Mandibular Complete Denture with Metal Reinforced Base: A Case Report The goal of restorative dentistry is to preserve teeth's natural structure and function while averting further issues with oral health. The most common treatment approach for rehabilitating one or two teeth is the insertion of a fixed dental prosthesis. This method offers a workable alternative for replacing lost teeth, and its longevity guarantees a long-term solution to prevent further oral health problems. To summarize, individuals with one or two missing teeth can have their smiles restored with a fixed dental prosthesis, which is a dependable, efficient, and effective method. To solve the prevalent problem of repeated prosthesis fractures, a single complete denture with a metal-reinforced base was utilised. This procedure offers a more durable and long-lasting solution for replacing lost natural teeth compared to traditional methods. This case study describes the thorough clinical treatment and fabrication of a pier abutment and metal denture base.

Purpose: Many methods have been used to treat complex fistulas, but no single technique has been considered standard. Damage to the sphincter may sometimes be unavoidable, and incontinence may be an important cause of morbidity. This study aimed to validate the results of transanal opening of the intersphincteric space (TROPIS), as a technique that avoids damaging the anal sphincter, in patients with complex fistula in ano. Methods: A prospective study was conducted among 35 consecutive patients with complex fistula in ano. After a preoperative magnetic resonance fistulogram, TROPIS was performed in all patients. The St. Mark’s incontinence score was assessed preoperatively and postoperatively at 3 months. Results: The tracts were intersphincteric in 16 patients, transsphincteric in 10, extrasphincteric in 2, and horseshoe in 3. Four patients had recurrent tracts (3 transsphincteric and 1 intersphincteric). A defined follow-up schedule was used. Curettage was done if postoperative pus drainage from the wound was noted. The fistula healed in 29 patients (82.89%) following TROPIS. The remaining 6 patients received curettage, with healing in 3 (overall healing rate, 91.4%). Patients who received curettage were followed for 3 months, and the outcome was labeled as healed or failed. The mean preoperative incontinence score was 0. One patient developed incontinence to gas postoperatively in week 2, but there was no significant change in the scores at 3 months postoperatively. The mean postoperative incontinence score was 0.02. Conclusion TROPIS is an effective method for the treatment of complex fistula in ano, with minimal risk for incontinence.
