Abstract

Implant supported removable partial denture (ISRPD) using the implants enables favorable rehabilitation by complementing biomechanical limitations of the conventional removable partial denture (RPD). However, continuous recall check is necessary for evaluation of the mechanical and biological complications to ensure good long-term prognosis of ISRPD. This clinical report describes the complication and management in patient of Kennedy class I edentulism with ISRPD using healing abutment. The wear and fracture of healing abutment occurred at 36 months after delivery. So, healing abutment was replaced by connecting Locator® abutment for altering into the implant retained partial overdenture.

Figure

  • Fig. 1 Initial panoramic radiograph.

  • Fig. 2 Postoperative panoramic radiograph. Two short implants were placed in mandibular posterior area.

  • Fig. 3 Anterior surveyed prostheses were cemented. No inflammatory signs were observed around healing abutment.

  • Fig. 4 Definitive removable partial denture was fabricated. Metal framework was adjusted to minimum contact with the healing abutment.

  • Fig. 5 Delivery of removable partial denture.

  • Fig. 6 (A) Occlusal view at 18 months after delivery. Mechanical wear was observed on flat surface of healing abutment, (B) At 30 months after delivery.

  • Fig. 7 Fragment of healing abutment was removed on mandibular right implant. Fracture of implant fixture was not observed.

  • Fig. 8 Old prosthesis was repaired. Blue nylon patrix was inserted.
