This retrospective clinical study aimed to evaluate the implants placed in fresh sockets and investigate the effect of varied oral health conditions and treatment plan details on the clinical and radiographic outcomes. Fifty-nine participants (102 implants) were included in this study. Four variables, including mean probing depth (PD), mean marginal bone loss (MBL), pink esthetic score (PES), and patient satisfaction, were significant dependent variables, and the effects of independent variables on these four items were studied. The data were analyzed by the analysis of covariance (ANCOVA) using a statistical software. The mean follow-up period was 4.75 ± 1.74 years, and the mean MBL was 1.21 ± 0.81 mm. The survival rate was 97 %. There were significant effects of the finish line site, keratinized gingival width, and attached gingival width on PD after adjusting the factors. Also, the implant brand, plaque index, and uncemented prosthesis affected MBL significantly. In addition, significant effects of the surgeon, implant brand, and proximal contact on PES were found. More PD was found around restorations with a finish line site > 1.5 mm subgingival. Sufficient attached gingiva was a more effective factor on PD than keratinized gingiva. Implants with more plaque scores showed more MBL. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The objective of the present case series with 24 months of follow-up was to document the clinicoradiographic status of IDI placed in fresh extraction sockets (FES) in the maxillary esthetic zone (MEZ). PATIENTS AND METHODS: Immediate implants were placed in the FES of three adult patients. Medical history and demographics of these patients were retrieved from their respective healthcare records. All extractions were done using atraumatic techniques and performed in the MEZ. Diameter and lengths of IDI ranged between 4-4.1 mm and 14-16 mm, respectively. Osseous drilling was done at 2000 rpm and implants were inserted using an insertion torque of 45 Ncm. All implants were restored with screw-retained ceramic restorations. Follow-up clinicoradiographic investigations were done after 2-years. At follow-up, peri-implant plaque and gingival indices were measured and peri-implant probing depth was measured. Marginal bone loss was also measured. RESULTS: The two-year follow-up clinical and radiographic results from all cases showed that the implant success and survival rates were 100% and 100%, respectively. There was no clinical evidence of peri-implant soft tissue inflammation in all cases. Scores of peri-implant plaque index, bleeding on probing, probing depth and crestal bone loss showed no evidence of peri-implant inflammation at 2-years' follow-up. All implants and their prostheses were clinically stable. CONCLUSIONS: It is concluded that IDI can osseointegrate and remain functionally and esthetically stable when placed in FES located in the MEZ. [ABSTRACT FROM AUTHOR]
