A comparative study on efficacy of immediate and delayed placement of cylindrical and tapered dental implants: A clinical prospective study

Introduction

The study deals with improving the understanding of implant design in various situations.

Materials and Method

40 implants were placed out of which 20 were tapered and rest were cylindrical. These were further divided into immediate and delayed settings. The patients were followed upto 6 months and the results were compiled.

Result

Statistically significant difference were found between tapered and cylindrical implants in terms of quality of osseointegration and maintenance of crestal bone height.

Conclusion

It has been gathered from the study that while delayed placement suggests waiting time period varying between 3 and 6 months, it offers a predictable procedure in terms of visibility, good implant-bone contact, and closure all of which, promote a better outcome for dental implant therapy. Immediate implant placement solution is very viable in reducing the time period involved in dental implant therapy. Apart from few to minimum contraindications, it can be predictably performed.

Proceedings of the 6th ITI Consensus Conference

The 6th ITI Consensus Conference was held in Amsterdam on 17-19 April 2018. In preparation for the conference, 21 systematic reviews were written. They were divided into five main topics in dental implantology-surgery, prosthodontics, patient-reported outcomes, complications/risk and digital technologies. Based on these review papers, the working groups prepared consensus statements, clinical guidelines and recommendations for future research.

Marginal and apical bone stability after staged sinus floor augmentation using bone condensing implants with variable-thread design: a two-dimensional analysis

Studies on the vertical stability of augmented bone after sinus lifting differ substantially. In addition, long healing periods are usually advocated prior to implant installation. The purpose of this case series study was to evaluate the changes in bone height after sinus lifting with a bovine-derived xenograft and to evaluate the clinical outcome of bone condensing implants installed after a short healing period. Patients treated during the years 2010-2013 were re-examined using peri-apical radiographs to evaluate the changes in augmented bone height (BH) and marginal bone loss (BL). Fifty-seven of 70 eligible subjects (28 male and 29 female, mean age 56 years) attended for reassessment. Data were available for 53 sinus lifts and 105 implants installed after a mean healing period of 4.6±1.5 months. Implant survival was 99% after a mean time in function of 19±9 months. Baseline BH, BH at implant placement, and final BH were on average 3.87±1.74mm, 13.75±2.12mm, and 13.11±2.12mm, respectively (P<0.001). Mean BL was 0.51±0.65mm. Only limited resorption is to be expected after sinus lifting in the short term. A bone condensing implant can be used in the early healing phase with successful outcomes in terms of implant survival and bone adaptation.
