![]() ![]() Whereas implant submersion continues throughout adult life, its rate varies with age. In the younger age group (≤30 years), the submersion rate was more than three times higher than in the older age group (>30 years), yielding submersion rates of 1.02 and 0.27% per year, respectively. Clinical photos from last follow-up were digitally analyzed to measure the vertical change between the incisal edge of the implant supported crown and the adjacent natural central incisor. The present study evaluated the effect of age on mean submersion rate of single dental implant in the central maxillary incisor area as compared with the adjacent natural tooth in implants placed after growth has ceased.Ī retrospective study was conducted on 35 patients (mean age 29.3 ± 9.9 years, 21 females) who received a single dental implant replacing a missing maxillary central incisor from 1992 to 2008 with a follow-up of at least 3 years. It is contraindicated to place dental implants before growth and development are completed as they are at a risk of submersion due to growth arrest, creating a potential aesthetic problem. It is contraindicated to place dental implants before growth and development are comp. significant differences in implant success rates were noted between genders, posterior. Dental implants placed in OBG showed a success rate of 93.7%, with most failures (78.2%) occurring at the prosthetic phase. Bone graft exposure was shown to be moderately associated with bone graft failure (χ2=3.76, p=0.052). Result: File data indicated that 254 OBG were successful (96.9%). Follow up time was up to 140 months (mean follow up time 44.4☓4.9 months). All the augmentations and implant placement procedures were performed by a single surgeon (DSA), and all the bone blocks were of intra oral origin (mandibular ramus and symphesis). Method: A retrospective study was conducted on 250 patients' files (mean age at OBG surgery 50.3☑5.5, 179 females) who received a total of 727 dental implants placed in 262 augmentations using OBG from 1999 to 2010. ![]() more Objective: Onlay bone grafting (OBG) using autologous bone blocks is an accepted method for the reconstruction of atrophic alveolar ridges.
