Zirconia Implants

Objectives. The aim was to evaluate survival and success rates, soft tissue health, and radiographic marginal bone loss (MBL) of zirconia implants placed in the esthetic and posterior areas of the jaws and in association with multiple or single implant restorations after at least 6 months of definitive restoration.Material and Methods. 35 one-piece zirconium implants were utilized for single or partially edentulous ridges rehabilitation. All implants received immediate temporary restorations and six months after surgery were definitively restored. Every 6 months after implant placement, a clinical-radiographic evaluation was performed. For each radiograph, the measurements of MBL were calculated.Results. The results showed that the mean MBL at 48-month followup was 1.631 mm. The mean MBL during the first year of loading was not more significant for implants placed in the first molar regions than for those positioned in other areas. Moreover, no differences in marginal bone level changes were revealed for multiple and single implants, whereas MBL in the first year was observed to be slightly greater for implants placed in the maxilla than for those placed in the mandible.Conclusion. Zirconia showed a good marginal bone preservation that could be correlated with one-piece morphology and characteristics of zirconia implants.

The Stability

ABSTRACT Purpose The long-term success of an implant depends on the stability of bone support for the implant. Most crestal bone loss occurs in the first year of implant placement. Platform-switching is an approach which can be clinically applied to preserve the crestal bone. The concept of ‘platform switching’ refers to the use of a smaller-diameter abutment on a larger-diameter implant collar. The purpose of the present study was to evaluate crestal bone level around platform-switched implants. Materials and methods Twenty implants with 5 mm diameter were placed in mandibular molar region. All implants had been placed at the crestal level at the time of surgery. Radiographs with grid were obtained 3, 6 and 12 months after loading and were evaluated by screen caliper software measuring the location of the crestal bone level relative to the implant platform. Results The implants showed a mean bone loss of 0.76 ± 0.1265 mm on mesial side and 0.72 ± 0.1481 mm on distal side after 1 year. Conclusion The findings of the current trial indicated that the use platform-switched implants lead to better preservation of crestal bone.

Abstract Objective Several modifications, such as changes in the implant–abutment connection, have been suggested in studies on dental implants to better preserve the peri-implant bone level. The aim of this study was to prospectively compare crestal bone level changes between two different implant designs—tissue level (TL) and bone level (BL). Materials and Methods The sample comprised 18 patients, on whom a total of 30 hydrophilic tissue- and bone level implants were placed (SLActive, Straumann Institut AG, Basel, Switzerland), in the posterior region of the maxilla or the mandible. Impressions were taken after 45 days of healing. Then, cemented-retained metalloceramic crowns were fabricated and installed. Marginal bone level changes were assessed by the paralleling technique of periapical radiographies, on both mesial and distal aspects of each implant, at the moment of the implant placement and after 1 year of loading. Photoshop software was used to perform linear measurements by a single and calibrated examiner. Statistical Analysis The Mann–Whitney test at a 5% significance level was used to compare the bone changes among the implants assessed. Results A significantly lower (p = 0.048) bone remodeling was observed on bone level implants (0.05 mm), when compared to tissue level implants (0.47 mm; p = 0.048). The average marginal bone level changes at the distal aspect did not show any statistically significant difference (p = 0.325). Conclusions Tissue level implants presented greater bone loss in the mesial surface than bone level implants. Both designs presented stable and clinically acceptable bone crests.

Introduction: The aim of this retrospective study was to analyze the radiographic peri-implant bone loss of bone level implants and tissue level implants with a convergent neck in screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of functional loading. Materials and methods: The sample was divided into two groups according to their type: Group I: supracrestal implants with convergent transmucosal neck; Group II: crestal implants. In each group we distinguish two subgroups according to the type of prosthetic restoration: single crowns and a three-piece fixed partial prosthesis on two implants. To quantify bone loss, parallelized periapical radiographs were analyzed at the time of implant placement and after two years of functional load. Results: A total of 120 implants were placed in 53 patients. After statistical analysis it was observed that for each type of implant bone loss was 0.97 ± 0.91 mm for bone level and 0.31 ± 0.48 mm for tissue level. No significant differences were found regarding the type of prosthesis and the location (maxilla or mandible) of the implants. Conclusions: Tissue level implants with a convergent transepithelial neck exhibit less peri-implant bone loss than bone level implants regardless of the type of prosthesis.
