The prevalence and associated factors of proximal contact loss between implant restoration and adjacent tooth after function: A retrospective study

Abstract

Background: Dental implant is widely used as a treatment for missing teeth. However, proximal contact loss (PCL) between implant-supported fixed dental prostheses (FDP) and adjacent teeth has been reported as one of the common and adverse complications.

Proximal Contact Loss in Implant‐Supported Restorations: A Systematic Review and Meta‐Analysis of Prevalence

“…Figure 3 illustrates the search workflow and the reasons for the exclusion of articles. Fifteen studies met the inclusion criteria 5,22–35 . A total of 11,699 restorations were evaluated in the final sample (Table 1).…”

“…Among the 15 included articles, 10 22,24–26,28,30,31,33–35 had a retrospective design and five 5,23,27,29,32 were prospective studies. Seven articles 5,23,25,28–30,32 included patients who had received or were scheduled to receive a single implant restoration, while eight articles 22,24,26,27,31,33–35 also included patients who had been rehabilitated (or were scheduled to be rehabilitated) with implant‐supported FPDs.…”

“…PCL was observed to be more common the longer the restoration had been in function, 22,28,30 with several articles stating that the peak period of PCL incidence appeared at 2 years, 27 while other articles described an increase in risk after 5 years 24,33 …”

“…Fifteen studies met the inclusion criteria. 5,[22][23][24][25][26][27][28][29][30][31][32][33][34][35] A total of 11,699 restorations were evaluated in the final sample (Table 1).…”

Annual review of selected scientific literature: A report of the Committee on Scientific Investigation of the American Academy of Restorative Dentistry

“…Several articles appeared in the 2020 dental literature addressing this clinical phenomenon. Liang et al 217 evaluated the prevalence of PCL up to 18 years after implant prosthesis placement and evaluated potential associated factors.…”
