Five-Year Study of Implant Placement in Regenerated Bone and Rehabilitation With Telescopic Crown Retained Dentures: A Case Report

subject

description

Abstract Various implant-supported restorations have been used successfully for several decades to rehabilitate edentulous patients. Telescopic crowns are a common treatment modality used to connect dentures to natural teeth. Although previous findings indicate that telescopic crowns can be placed successfully on implants to support overdentures, only limited data are available on this treatment approach. Eight months after extraction of all nonsalvageable teeth and socket preservation, 11 implants were inserted into the mandible and maxillae of one patient. These implants were restored 4 months later using telescopic crown–supported dentures. Bleeding on probing (BOP), plaque index (PI), clinical attachment (PAL), and radiographic bone level were evaluated over 5 years. All implants remained in function over the 5-year evaluation period. Radiography showed stable bone levels for all implants. No changes in BOP or PI (range, 2%–4% for both parameters) were observed over this time. The PAL deteriorated by 1.5 mm during the first 3 years, with no subsequent changes. We conclude that telescopic crowns can be used successfully as attachments for overdentures supported by implants in regenerated bone.
