Prosthetic Rehabilitation using a Telescopic Crown constructed with Computer-assisted Design and Computer-assisted Manufacturing: A Case Report with a 2-year Follow-up

: Aim and background: This case report describes a 74-year-old female patient whose teeth were rehabilitated using telescopic crowns (TCs) on abutments and fixed dental prostheses (FDPs) in the maxillary arch with the aid of computer-assisted design and computer-assisted manufacturing (CAD/CAM) technology. The mandibular arch was restored using casted removable dental prostheses (RDPs) and surveyed crowns. Case report: The treatment sequences were followed as recommended in the dental literature. First, existing defective restorations were eliminated, caries was removed, and excellent mouth preparation was performed. Subsequently, root canal treatments and post and core placements were conducted. The casts were mounted, and a new vertical dimension was established. Maxillary telescopic FDP and mandibular prostheses were fabricated. Finally, a regular and proper follow-up and maintenance program was implemented. Conclusion: The patient was satisfied with the esthetics and function of the telescopic FDP in the presence of the established occlusion. Clinical significance: The secondary coping of the telescopic FDP is cemented with temporary cement, which can be changed easily whenever it is loose. Furthermore, it is completely opposed to RDP in the mandibular posterior masticatory area. The prognoses will be good improvement; the patient was medically fit, motivated, and followed continual oral hygiene protocol.
