Salvage of Dental Implant Located in Mandibular Odontogenic Cyst. A Conservative Surgical Treatment Proposal

Abstract

The aim of this case report was to evaluate the use of Partsch I cystotomy in order to preserve a dental implant located in an odontogenic cyst extended from 3.2 to 4.4. A 50 year-old woman showed a circular, well-defined unilocular radiolucent area, Ø2.5 cm, in the right mandibular region with an oral implant intruding inside it. The overdenture in the mandibular right site showed no clinical mobility. The authors decided to perform a surgical treatment aimed to preserve the implant. The patient underwent Partsch I surgery followed by iodoform gauze insertion replaced weekly for one month, revision of the previous orthograde endodontic treatments, and an acrylic resin obturator prosthesis application for the following two months. The twelve month follow-up showed no clinical mobility of the right lateral mandibular implant prostheses. Radiographical analysis revealed cystic lesion healing and perimplant bone regeneration. This report highlights the opportunity to apply cystotomy when the cyst involves a dental implant and undermines its stability. This possibility is offered by the peculiar clinical scenario where the implant was stabilized by the presence of a previous prosthetic fixation. Our study led to the application of an operative protocol that allowed for the preservation of the implant.

COVID-19 and the Impact on the Cranio-Oro-Facial Trauma Care in Italy: An Epidemiological Retrospective Cohort Study

“…A systematic review described the COVID-19 as an infectious disease that primarily affects the lungs. Its multi-organ involvement is responsible for several prolonged symptoms, including oral implications [ 29 , 30 ]. In recovered patients, the prolonged symptoms can delay the elective treatments.…”

A novel histopathological classification of implant periapical lesion: A systematic review and treatment decision tree

“…Table 2 showed the information of IPL extracted after retrieval. There were 27 case reports [ 6 – 8 , 12 – 34 ] and 1 retrospective study [ 35 ], all of which were conducted in humans. The following signs and symptoms were frequently mentioned in the case reports: swelling, abscess, localized pain, and fistula.…”

“…As Table 1 shows, there is still no consensus on the classification of IPL. The included reports (70 patients/76 implants) were preliminarily distributed in Penarrocha-Diago et al ’s classification [ 5 ]: 31 implants were inactive [ 8 , 12 , 13 , 17 , 18 , 20 , 21 , 26 , 27 , 29 , 30 , 33 , 36 ], and 46 implants were active, with acute non-suppurated(1) [ 13 ], acute suppurated (10) [ 6 , 7 , 14 , 16 , 19 , 25 , 28 , 31 , 32 ], subacute/suppurated-fistulized(7) [ 15 , 22 – 24 , 33 , 34 ], unclear stage(26) [ 35 ]. It should be noted that histopathological findings in some cases did not match Penarrocha-Diago et al’s classification to some extent.…”

Large Follicular Cyst Associated with Upper Third Molar in the Maxillary Sinus with Pterygomaxillary Space Extension: Reflection on a Case Report

“…Radiologically, follicular cysts have a typical appearance, showing as unilocular radiolucent lesions with well-defined sclerotic borders [6]. This appearance, however, is not pathognomonic and odontogenic keratocyst, radicular cyst, adenomatoid odontogenic tumor, ameloblastoma, calcifying odontogenic cyst, and ameloblastic fibroma which may present same radiographic property [10]. Therefore, histopathologic investigation is mandatory for final diagnosis [11].…”
