Due to severe alveolar ridge atrophy, mini\u2010implant insertion (2.0\u2009mm wide) was an option without extensive surgical procedures. The patient signed the informed consent. A few days after the implant insertion, injury, inflammation, and induration of the vestibular movable mucous membrane were observed on the movable vestibular mucosa on the right side, opposing the mini\u2010implants. The cause of inflammation was attributed to increased perioral muscle tonus which pushed the movable mucosa onto the mini\u2010implant heads and caused mechanical trauma. During the period of edentulism, the perioral muscle tonus increased, directing the mucous membrane of the lips and cheeks against residual ridge to enable food comminution. To treat the persistent decubitus, a bulk of dental composite resin was placed around mini\u2010implant heads and light\u2010cured to protect the mucosa from further mechanical trauma, as the patient did not possess an old mandibular denture to cover the mini\u2010implant heads. Vestibuloplastic surgery (disinsertion of movable attachments and deepening of the vestibulum) was also done. After the surgery, a silicone splint, resembling an occlusal rim, was made to protect the mucous membrane, keep medicaments for faster epitalization in place, to decrease perioral muscle tonus before the new dentures\u2019 delivery, and to prevent movable tissue relapse. The custom impression, jaw relationship determination, and try\u2010in of the artificial teeth setup were made with sutures still in place. After the denture delivery and implant loading, the patient was instructed to sleep with the dentures to protect the movable mucous membrane. One year later, almost no peri\u2010implant marginal bone loss was observed, attached and peri\u2010implant mucosa were healthy, and the patient was delighted.<\/jats:p>","DOI":"10.1155\/2024\/4662194","type":"journal-article","created":{"date-parts":[[2024,10,24]],"date-time":"2024-10-24T08:19:03Z","timestamp":1729757943000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Traumatic Ulceration of the Vestibular Mucous Membrane After Insertion of Four Mini\u2010Implants in the Atrophied Mandible: A Case Report"],"prefix":"10.1155","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5432-3364","authenticated-orcid":false,"given":"Domagoj","family":"Kili\u0107","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0338-9643","authenticated-orcid":false,"given":"Sanja","family":"Per\u0161i\u0107-Kir\u0161i\u0107","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5985-8966","authenticated-orcid":false,"given":"Asja","family":"\u010celebi\u0107","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,10,24]]},"reference":[{"key":"e_1_2_10_1_2","first-page":"892","article-title":"Multi-clinic evaluation using mini-dental implants for long-term denture stabilization: a preliminary biometric evaluation","volume":"26","author":"Bulard R.
