Implants Placement in Contact with Dental Tissue: A Potential Paradigm Shift? Systematic Literature Review

et al. 2019

View full text Add to dashboard Cite

The aim of this study was to explore the literature for clinical and histological data of an unconventional treatment with implants placement in contact with dental tissue (IPICDT) and to try to clarify its indications and surgical procedure particularities.Relevant publications published until May 2019 on the IPICDT were thoroughly reviewed. Search strategy was developed using a controlled vocabulary combination.Medline’s exploration and manual research identified 397 articles; 15 of these were selected after screening. IPICDT was indicated in three clinical situations: impacted teeth, ankylosed teeth, or residual roots. Clinical and radiological follow-up were satisfied except for implants placed in contact with (and not through) roots. Histological analysis revealed different mineralized tissues formed on the implant surface: cementum on removed implants in human and osteodentin on implants placed in contact with animal teeth dentin and pulp. These findings were described as new concept of implants’ “Mineral integration.”According to this study, the follow-up results of implants placed in contact with roots were controversial. Some implants were stable and others were either removed or kept and disinfected after root extraction because of bacterial infection. However, implants placed through ankylosed or impacted teeth were stable. These findings suggest that the clinicians have to be cautious when applying this unconventional approach. Further studies are recommended to explore its long follow-up. It is also interesting to explore this technique in cases of syndromic dental diseases with several impacted teeth (such as cleidocranial dysplasia; or amelogenesis imperfecta).

“…The surgeon needs to be specially trained and possess a high degree of clinical skill because the surgical procedure requires more time and patience. Finally, although implant failure and complication rates were low in the current metaanalysis, some studies [43,44] have reported a case series documenting late implant complications and failures after 4-10 years of loading, which indicates the potential long-term risks of SST. Complications such as RM migration, exposure, or inflammation may lead to soft tissue defects, pocket formation, mucositis, and peri-implantitis.…”

Socket shield technique: A systemic review and meta-analysis

et al. 2022

The aim of the present study was to evaluate the clinical feasibility of the socket shield technique (SST). Study selection: An electronic search of the PubMed, Cochrane Central Register of Controlled Trials, and Wiley Online Library databases, and a manual reference search for articles published up to September 2020 was conducted. Meta-analysis was performed to estimate marginal bone loss (MBL), changes in buccal bone width (cBBW), pink esthetic score (PES), implant stability quotient (ISQ), implant failure rate, and complication rate between SST and conventional immediate implant placement (IIP). All pooled analyses were based on random effects models. Results: Sixteen relevant studies were ultimately selected by two independent reviewers: four randomized clinical trials (RCTs), four case-control studies, and eight retrospective studies. Meta-analysis revealed a trend toward lower MBL and cBBW and higher PES in the SST group. ISQ, implant failure rate, and complication rate were similar between the groups. Conclusions: The included studies provided evidence that SST may be a feasible treatment option. However, this technique should not be used as a routine clinical protocol due to the lack of evidence-based consensus guidelines, large-scale RCTs, and long-term follow-up data. Therefore, there is an urgent need for well-conducted RCTs in this field.

“…Nevertheless, recent articles by Nevins et al 22 and Langer et al 23 reported belated implant failures when placed through impacted root remains. Scanning electron microscopic evaluation revealed that the failed implant surfaces were infiltrated by bacterial deposits and calculus.…”

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

et al. 2020

View full text Add to dashboard Cite

Multiple dental impactions not associated with craniofacial syndromes are a rare condition and present the dentist with a therapeutic challenge when it comes to performing surgical/restorative treatments in adult patients. This case report describes a geriatric patient with multiple impacted teeth restored by means of two different protocols. In the second quadrant, an impacted tooth was extracted followed by regeneration and placement of an implant. In the third quadrant, implants were placed though impacted teeth for restoration with a fixed partial prosthesis. Placing dental implants through impacted teeth may offer a possible therapeutic option for implant-supported restorations in middle-aged or elderly patients, for whom surgery and orthodontic traction are not possible, and/or patients who refuse to undergo more invasive extraction surgery.
