    The effect of implant characteristics on the implant stability of immediately loaded single implant cases: A prospective study
    (2018) Obagbemiro, K; Ajayi, Y O; Akeredolu, P A; Adeoye, JA; Arotiba, GT
    Introduction: Factors that affect primary and ultimate implant stability include characteristics of the type of dental implant used, bone quality at the site of implant placement, insertion torque, as well as micromotions at the bone–implant interface. This study, however, sought out to determine the effect and relationship between relevant implant characteristics and implant stability in immediately loaded single implant cases using the Periotest® M handheld device. Aim: To determine the effect of implant characteristics on the ultimate implant stability in immediately loaded single implant cases. Results: At placement, 33 (94%) of implants had periotest values between −0.8 and 0 at placement. There is a general decrease in the number of patients with periotest values −0.8–0 and those with +1–9 from the initial placement to 6 months after placement. It was further observed that there is a negative correlation between the implant length, diameter, and the mean periotest values although this was not statistically significant. Conclusion: There is a directly proportional relationship between implant characteristics and implant stability of immediately loaded implants.

    Evaluation of short term survival rate of immediate loading of single implant cases in Nigerian subjects : A longitudinal study
    (2019-06) Obagbemiro, K; Ajayi, YO; Adeoye, JA; Akeredolu, P A; Arotiba, G T
    Objective: Dental implant therapy is fast becoming the most popular treatment option for replacing missing teeth. The original protocol for its placement advocates leaving the implant unloaded for a three to six-month period before placing the prosthesis. In more recent times, loading implants right after they are placed within the bone have been achieved, offering several advantages to the patients. This study aims to evaluate the one-year survival rate of immediately loaded dental implants. Materials and methods: This prospective, longitudinal and interventional study evaluated the one-year survival rate of immediately loaded single dental implants cases in 35 subjects that were rehabilitated using the one stage implant protocol. Subject follow up was done for at intervals over a one-year period with data collected at each visitation. Analysis of data gathered was done using Statistical Package for the Social Sciences software (SPSS) version 22 (IBM Corp, Armonk, NY, USA). Results: A cumulative survival rate of 80% was obtained with 28 out of 35 implants surviving after the one-year review period. All mandibular implants survived while a survival rate of 72% obtained in the maxilla. Furthermore, 87.5% of immediately loaded implants placed in the posterior region survived, which is higher than the 73.7% implant survival rate observed in the anterior region. Conclusion: Provided the conditions are favourable for its use, immediately loaded implant protocol should be considered as the protocol has a one-year survival rate that compares favorably with the conventional protocol for implant placement.
