Fabrication of a closed hollow bulb obturator for the rehabilitation of an acquired partial maxillectomy defect due to mucormycosis

Patient affected from post-COVID mucormycosis often require local debridement or surgical resection resulting in maxillectomy. This is frequently quite extensive or bilateral and spares very little of the hard and soft tissues in the oral cavity. Both surgery and prosthetic rehabilitation are needed to rehabilitate such extensive defects. Once the patient has grown accustomed to the temporary prosthesis and effective healing has taken place, a definitive prosthesis is inserted for the patient. Definitive obturators require careful thought during design to ensure longevity and superior retention and stability. This article documents the prosthetic rehabilitation of a partial maxillectomy defect due to mucormycosis which resulted after COVID

Comparative evaluation of the virtual planned position and actual position of implant in mandibular posterior region using a DIOnavi system: An in-vivo study

Statement of problem: Implant placement in the mandibular posterior regions is often challenging because of limited space and insufficient accessibility. Purpose: The purpose of this clinical study was to investigate the accuracy of computer-guided surgery with a long drill key to place implants in the mandibular posterior regions. Material and methods: Computer-guided implant surgery was performed for 15 participants requiring implants in mandibular posterior region. This procedure involved using 6mm long drill key to guide the 2.0 mm diameter drill. The planned and placed implant position were scanned and superimposed to evaluate the accuracy of the guide. Results: A total of 15 implants were place where the mean linear deviation was 0.4 mm (range, 0.15 to 1.30 mm) for the implant shoulder and 0.45 mm (range, 0 to 1.48 mm) for the implant apex. The mean angular deviation was 1.4 degrees (0.38 to 4.89 degrees). The mean depth deviation was 0.61 mm (0.10 to 1.85 mm). The differences between virtually planned implants and actual positions of the implants were statistically significant for all variables (P<.05)

Fiber-Reinforced Composite-Fixed Partial Denture: A Case Series

In most societies, lack of anterior teeth is a serious problem in a patient’s social life. While traditional removable partial dentures and implant support restorations are often the treatment of choice, fiber-reinforced composites are a conservative, fast, and cost-effective alternative for single and multiple tooth replacement

Laser functionalization: An emerging modality to enhance the osseointegration potential of polyetheretherketone as a dental implant material

The unique physical and mechanical attributes of polyetheretherketone (PEEK) have lent significant momentum to the motion that PEEK can be used as a material of choice for dental implants. However, in contrast to titanium or zirconia, PEEK has very limited inherent osteoconductive properties. A wide variety of research has been conducted till date to improve the bioactivity of PEEK surface. Varied methods have been proposed, laser surface treatment of PEEK being one of the promising techniques. Data collection was limited to the last 10 years from 2012 to 2021. Eleven articles were found suitable for this review found in the databases of PubMed and Google Scholar. Considerable alterations have been observed in surface roughness and wettability characteristics of PEEK after laser surface treatment, which improved the osseointegration property of PEEK to be utilized as a dental implant material. The current paper is aimed at reviewing different types of laser applications to the PEEK surfaces and its effect on bone-to-PEEK implant contact
