Prosthodontic Rehabilitation with Digitally Designed Mandibular Telescopic Denture Using DMLS Technology: A Case Report

Abstract

The rehabilitation of partially edentulous patients involves a variety of prosthetic options, each tailored to individual clinical and financial considerations. While fixed solutions like dental implants and bridges are often preferred for their stability, they may not be suitable for all patients due to cost, anatomical limitations, or oral health conditions. This case demonstrates successful prosthodontic rehabilitation combining conventional and digital techniques. A 70-year-old male patient presented with a completely edentulous maxillary arch and partially edentulous mandibular arch retaining teeth. Previous conventional dentures were discontinued due to poor fit and esthetics. A hybrid prosthodontic approach was selected: conventional maxillary complete denture and digitally designed mandibular telescopic denture using DMLS (Direct Metal Laser Sintering) technology. Following endodontic treatment and tooth preparation, primary cobalt-chromium copings were cemented. The mandibular framework was digitally designed using Exocad software and fabricated via DMLS technology with ceramic-layered secondary copings. Telescopic dentures offer superior retention and stability compared to conventional removable partial dentures through precision-fit primary and secondary crowns that distribute occlusal forces uniformly. DMLS technology provides high-strength, biocompatible frameworks with excellent fit and minimal material waste while eliminating casting errors. Digital workflows improve accuracy, reduce clinical time, and enable prosthesis archiving for future duplication. The telescopic mechanism preserves periodontal proprioception, reduces residual ridge resorption, and provides secondary splinting of abutment teeth. This approach is particularly valuable when implant therapy is not feasible due to patient factors or economic considerations. The patient showed excellent functional outcomes with improved chewing ability, speech, and esthetics at follow-up appointments. DMLS-fabricated telescopic dentures provide predictable clinical results with superior mechanical properties and enhanced patient satisfaction. This treatment modality represents a viable alternative to implant-supported prostheses for complex edentulous cases, offering improved quality of life while being more economically accessible.
