Single Tooth Implant

Single tooth implant restorations in the aesthetic area are a demanding challenge. If a complete osseointegration is mandatory, the final result has to result in a higher standard of biomimetic and soft tissue health among natural teeth. This outcome is traditionally pursued by cementing crowns over individualized abutments. However, in recent years, the need for controlling peri-implant health and the preference towards a retrievable solution has led to an increase in screw-retained crowns, which is not always applicable when the implant axis is not ideal. In the aesthetic area, the use of a novel technical solution represented by the angled screw channel (ASC) of the abutment has been proposed in order to match the advantages of the screwed solution with the aesthetic demands. The aim of this study was to compare ASC crowns to cemented crowns (CC) in single implant restorations using the white esthetic score (WES) and pink esthetic score (PES) at the crown delivery and at a follow-up of a minimum of 2 years. Peri-implant health and marginal bone loss (MBL) were also evaluated. The mean follow-up was 44.3 months, with a mean MBL of 0.22 mm in the ASC group and 0.29 mm in the CC group. The total WES/PES score was 16.6 for ASC, compared with 17.3 for CC at baseline, and 16.2 and 17.1, respectively, at follow-up. Both of the groups reached a high WES/PES, and this was maintained over time, without signs of peri-implant diseases or bone loss, regardless of the choice of connection. In conclusion, ASC can be adopted in cases where the implant axis is not ideal, with aesthetic and functional results that are comparable to implants restored by cemented crowns.

Abstract This study was undertaken to evaluate the effect of microthread geometry of scalloped design implant on marginal bone resorption. Four types of scalloped design titanium implant specimens were prepared. The type 1 implant had a machined scalloped collar, type 2 had a sandblasted and acid-etched scalloped collar, type 3 had horizontal microthreads, and type 4 had parabolic microthreads, which are parallel with the scalloped conical margin. Two implants of a type were randomly installed immediately after extraction in the mandible of a beagle dog. Definitive prostheses were delivered immediately after surgery. After 12 weeks of healing, the dog was sacrificed and microtomography was performed. Type 4 specimens showed a marginal bone loss pattern definitively analogous to the scalloped margin. In this preliminary study, microthread geometry affected the marginal bone resorption pattern of scalloped design implants. However, additional specimens and more controlled conditions should be applied in future studies to confirm these results.

AIM: To evaluate and compare the marginal bone loss and aesthetic outcomes of zirconia implants with titanium implants in randomized controlled trials (RCTs). MATERIAL AND METHODS: Electronic [PubMed] and hand searches were performed to identify randomized controlled trials that were published between January 2008 to April 2020 which investigated and compared various outcomes between zirconia and titanium dental implants. Outcomes included assessment of marginal bone loss and aesthetics using spectrophotometric measurements. Meta-analysis was performed to estimate the above parameters among various studies. RESULTS: A total of 58 articles were screened for titles and abstracts. Subsequently 8 articles were selected for data extraction and evaluation. Zirconia implants were investigated and compared to titanium implants for marginal bone loss [MBL]. Customized zirconia and titanium abutments seated over implants were analyzed for aesthetic outcomes using spectrophotometric method using CIE-Lab measurements. Meta-analysis estimated that zirconia implants exhibited marginal bone loss reduction of 0.179mm (95% CI, 0.02 to 0.33) and -0.242mm (95% CI, -4.026 to 3.542) in aesthetic measurements than titanium implants. CONCLUSIONS: No heterogeneity was observed among studies analyzed for marginal bone loss and significant differences were noticed between two groups. Noticeable heterogeneity was observed among studies assessing aesthetics using spectrophotometry and CIE-Lab measurements and results revealed no many significant differences between the two groups.

Objectives. Bitewing radiographs are mainly used to confirm clinical findings in caries diagnostics. The objective here was to investigate the quality of bitewing radiographs after short brush-up training and additional findings besides caries in a low-caries population. Methods. The material of this cross-sectional study comprised 377 pairs of bitewing radiographs of 19- to 20-year-olds taken by dentists. Radiography was considered indicated if one dentinal caries lesion was present on clinical examination. A senior oral radiologist evaluated quality and diagnosed the findings afterwards unaware of clinical status. The association between variables was analysed using cross tabulation and chi-squared testing. Results. Almost half of the images were of compromised quality (44.1%). Dentinal caries lesions were detected in 82.3% and enamel lesions in 73.5% of the subjects. On average, the subjects had 1.7 (SD 0.52) dentinal lesions. Fillings were found in 81.8%, fractures/cracks in 11.7%, and attrition in 7.4% of the subjects. Signs of excessive bite force were recorded in 19.4%, whereas marginal bone loss was detected in 6.4%. No significant correlation was detected between fractures, attrition, and excessive bite forces. Conclusions. Effort must be taken to ensure high quality of bitewing radiographs. In addition to caries detection, bitewing radiographs offer additional value, such as detecting excessive bite forces, tooth wear, and marginal bone loss among young adults.

Background. This study evaluated the viability of platelet-rich plasma for enhancement of osseous and associated soft tissue healing around single-piece implants, subjected to immediate loading and to compare it with a control site not treated with PRP. Methods. Twenty completely edentulous patients were selected and 2 one-piece implants with O-ball head were placed for mandibular overdenture. The implant on the right side was treated with PRP whereas the left side implant served as a control. All the cases were immediately loaded and marginal bone loss, probing depth, percussion, implant mobility and peri-implantitis were assessed and compared at 3, 6, 9 and 12 months. Results. Overall analysis of the results showed less marginal bone loss, probing depth, percussion, implant mobility and periimplantitis around implants treated with PRP; however, the results were insignificant statistically. Conclusion. PRP can be used as a viable treatment adjunct in immediately loaded one-piece implants.
