Unconventional Implant Placement Part III: Implant Placement Encroaching upon Residual Roots – A Report of Six Cases

Abstract

Several types of new implant-tissue interfaces were created in addition to the classical implant-bone interface, but this did not seem to jeopardize implant integration. Reports of more cases with a longer follow-up are needed before this protocol can be endorsed for routine application. Nonetheless, if confirmed as acceptable, this protocol might open intriguing possibilities; it might also lead to revision of one of the leading concepts in dental implantology.

Evaluation of dental panoramic radiographic findings in edentulous jaws: A retrospective study of 743 patients "Radiographic features in edentulous jaws"

“…Today, recent studies suggested an implant placement protocol encroaching upon residual roots and impacted teeth. 19 20 This unconventional method has been proposed to assess minimal invasive surgical procedures in implant dentistry. However, future research needs to be investigated for this procedure.…”

Unconventional Implant Placement IV. Implant Placement through Impacted Teeth to Avoid Invasive Surgery. Long-term Results of 3 Cases

“…At the beginning, a clinical relevance has been related to 3 distinct indications. Their common goal was to avoid invasive surgeries; they were: placing implants through impacted teeth [ 4 , 7 ], ankylosed teeth [ 3 , 7 ] and residual roots [ 7 , 8 ]. But other authors found it applicable to address esthetic issues in order to maintain an optimal support to the marginal gingiva [ 9 ] or the papilla [ 10 ].…”

“…Since then, more cases with impacted teeth have been successfully treated [ 5 , 6 ] and the principle governing these protocols has been extended to inserting implants through residual roots [ 7 , 8 ] or in contact with radicular dentine while seeking to optimize esthetics [ 9 , 10 ]. The biological rationale of bringing implants into contact with dental tissues has been extensively addressed elsewhere [ 3 - 6 ]; it was found to get a trustworthy support from available histological data.…”

Placing Dental Implants through Impacted Teeth to Support a Fixed Partial Denture in a Geriatric Patient as an Alternative to Invasive Extraction Surgeries

“…[19][20][21] Microscope studies have affirmed the appearance of periodontal ligament with a layer of cementum over the implant surface occupying a space containing the collagen fibers and blood vessels characteristic of periodontal ligament. 20,21 On the basis of these findings, Davarpanah and Szmukler-Moncler [8][9][10][11][12] published a series of articles (the first in 2009) describing a case series in which implants were placed through ankylosed impacted root remains or impacted teeth. The authors suggested that this alternative to the conventional bone-to-implant interface would not interfere with the implants or their mid-to long-term survival.…”
