Single-crown restorations in premolar-molar regions: short (<= 6.5) vs longer implants: retrospective cohort study

Purpose To compare the survival, changes in marginal bone level and prosthetic complications rate of short (<= 6.5 mm) and longer implants (>= 7.5) supporting a single-crown restoration in the maxillary/mandibular premolar or molar region. Methods This cohort study was conducted following the...

Methods This cohort study was conducted following the STROBE statement recommendations for observational studies. Clinical outcomes of 88 short implants in 78 patients and 88 long implants in 88 patients were examined. All the implants had been placed by the same surgeon and restored following the same prosthetic concept; using a transepithelial abutment (intermediate abutment) and a screw retained restoration. Results All the implants were in function after the follow-up period since insertion (median: 31 months; range 11 to 84 for SiG vs median: 35 months; range: 6-117 for CG; p = 0.139). No statistical differences (p = 0.342) were observed related to prosthetic complications (screw loosening 2/88 vs 5/88 CG, ceramic chipping 1/88 vs 0/88, temporary crown resin chipping 1/88 vs 0/88 for SiG and CG, respectively) or related to marginal bone level (Mesial or Distal MBL >= 2 mm in 1/88 implants for SiG vs 3/88 for CG; p = 0.312). Conclusions Within the limitations of this study, no survival differences have been observed between short implants and longer implants in single-crown restorations in posterior maxilla/mandible.Springer202220222022info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10810/58603reponame:Addi.
