It synthesises current literature and clinical guidelines to highlight four core pillars, namely mucosal seal, individualised implant positioning, collar design optimisation and harmonised integration of soft tissue and restoration, and is thus referred to as the MICH concept. Particular emphasis is placed on the biological importance of adequate peri-implant mucosal thickness (≥ 2 mm) for maintaining a stable soft tissue seal and reducing the risk of marginal bone loss. The review further highlights the anatomical and biological foundations of supracrestal tissue height adhesion, supporting the clinical significance of personalised implant placement and collar design for maintaining peri-implant health. By addressing both biological and prosthetic aspects, the MICH framework advances beyond the established PROS concept for bone-level implants that encompasses the principles of platform switching, restorative abutment design, optimal (internal conical) connection and subcrestal implant placement, offering clinicians clear guidance tailored to the unique challenges posed by tissue-level systems.

{"title":"Molar replacement revisited, from standard bone-level to tissue-level implants with an individualised design: Case report with a 36-month follow-up period.","authors":"Roland Glauser","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>When a tooth is lost, resorption of the surrounding hard and soft tissue occurs. If the tooth is not replaced, the bone in the area gradually deteriorates owing to the lack of functional stimulation. Replacing a tooth shortly after its loss with a fixed implant-supported restoration can help mitigate these consequences. This is particularly crucial for a first molar, which, being a primary load-bearing point, plays an essential role in the proper development of the permanent dentition and in masticatory function. Various approaches exist for implant-supported replacement of a first molar, but each has limitations in terms of cleansability, treatment cost and biomechanical performance. This case report explores a newer, clinically proven approach involving a two-piece large-diameter tissue-level implant that features an individualised neck and platform contour instead of the typical circular shape, ideally corresponding to the dimensions of the molar edentulous space. The report involves a 63-year-old man who underwent this treatment 5 years after extraction of the mandibular left first molar, and details the treatment planning, surgical procedure and prosthetic restoration. The treatment outcomes, observed over a 36-month follow-up period, were a stable marginal bone level, healthy and stable soft tissue and satisfactory aesthetics. This demonstrates that this implant can be considered the method of choice for first molar replacement.</p>","PeriodicalId":73463,"journal":{"name":"International journal of oral implantology (Berlin, Germany)","volume":"19 1","pages":"77-88"},"PeriodicalIF":2.5,"publicationDate":"2026-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147446204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
