Proximal contact loss between implant prostheses and adjacent natural teeth: A qualitative systematic review of prevalence, influencing factors and implications

A two-year prospective study to compare the peri-implant parameters of posterior implant-supported single crowns with and without mesial proximal contact loss

“…Though some studies had revealed various post-treatment biological, mechanical and technical complications, such as screw loosening, fracture or wear of superstructure implant components, marginal bone loss, implant loss, porcelain fracture or porcelain chipping and so on. 1 , 2 , 3 , 4 , 5 , 6 In daily practice, receiving food impaction over the implant site could be one of the common patients’ compliant and this could be attributed to the loss of interproximal contact between implant-supported fixed dental prostheses (FDPs) and the adjacent teeth.…”

“… 13 , 15 , 16 Interproximal contact loss may lead to food impaction, and results in subsequently complications such as periodontal defects, 13 , 17 , 18 recurrent decay, 19 and peri-implant tissue complications. 2 , 19 , 20 In terms of periodontal tissue, some studies reported that interproximal open contacts were related to clinical attachment loss, deeper probing depths, and processing bone loss. 2 , 17 , 21 , 22 Peri-implant tissue is more susceptible to pathosis in comparison to natural teeth, because only the circular arrangement of periodontal fibers seals the mucosa around dental implant.…”
