Ten Years Follow-Up of Sputtered Hydroxyapatite Coated Implant in Single or Two Missing Teeth Replacement

Abstract

Sputtered hydroxyapatite coated implant has investigated as an implant with novel surface coating for dental implant. The aim of this study was to evaluate the 10 years clinical outcome regarding marginal bone loss around implants, success rate, survival rate, biological and prosthetic complication and patients subjective satisfaction for the implant with sputtered hydroxyapatite coating in human. Sixteen patients with 30 implants were employed for this study. One-piece, sputtered hydroxyapatite coated implants were placed in premolar and/or molar sites with one or two missing tooth. Ten years after implant placement, the marginal bone level change was evaluated by periapical radiograph. Incidence of peri-implant diseases and prosthetic complications were also addressed. Patient satisfaction was analyzed by Oral Health Impact Profile questionnaire. The mean marginal bone loss was 0.74 ± 1.41 mm. Survival and success rates were 96.7% and 86.7% respectively. Three implants (10.0%) in 3 patients (18.8%) were affected by peri-implantitis. Five implants (16.7%) in 4 patients (25%) had chipping of veneering material on prosthesis. One implant (3.3%) in a patient (6.3%) was fractured and removed. Mean score of Oral Health Impact Profile was 41.6 ranged from 3 to 89. Sputtered hydroxyapatite surface showed comparable marginal bone stability in 10 years result.
