“…So far, the Caldwell-Luc technique or lateral window technique [29] has been reported to cause greater surgical invasion and the occurrence of a postoperative cyst [23,27,49,56,57]. However, ES is less surgically invasive and less likely to cause postoperative cysts [27,58].…”

Purpose: This study aimed to evaluate differences in 10 items of treatment details in patient regarding cases between 2015–2017 (EP) and 2018–2020 (LP) from scoping literature review of displaced dental implant (DDI) retrievals. Materials and methods: PubMed, Google Scholar, and ScienceDirect were searched using key words including “displaced,” “retrieved,” “migrated,” or “accidental" dental implants. Treatment details were analyzed for the differences between EP and LP in 92 cases from 32 articles published in 13 countries. Statistical significance was evaluated using the Mann-Whitney U-test, Fisher’s exact test, and Pearson’s correlation analysis. Results: In the comparison between EP and LP, there was no significant difference in the number of publication countries (11 vs. 10), number of published articles (17 vs. 15), distributions of cases (50 vs. 42), mean age of patients (55.9 ± 1.8 years vs. 55.3 ± 2.5 years), male-female distribution (31/19 vs. 24/18), and distribution of displacement into the maxillary sinus and other regions (46/4 vs. 34/8), and no significant difference in the Pearson’s correlation between publication years and the number of articles. DDI retrievals utilized intraoral and endoscopic surgeries (61.2% and 82.5%), transoral and transnasal approaches (93.8% and 81.8%), and local and general anesthesia (64.7% and 76.3%) during EP and LP, respectively. Moreover, significant differences were observed in all distributions between the two factors (30/19 vs. 7/33 cases, 30/2 vs. 6/27 cases and 2/12 vs. 9/29 cases) in EP and LP, respectively (P < 0.01). Conclusions: These results suggest that most DDI retrievals in otorhinolaryngology since 2018 have been mostly performed using transnasal endoscopic approaches under general anesthesia.

“…Otherwise, we would suspect that a residual odontogenic cyst owing to incomplete removal during tooth extraction might migrate into the maxillary sinus. Some reports have described patients with POMC whose dental implant was successfully preserved via the enucleation of the POMC [8] , [9] , [10] , [11] , while in others, the preservation of the dental implant by the enucleation of both the POMC and the implant close to the POMC was impossible [12] , [13] . Thus, debate still exists as to whether the preservation of the dental implant close to the POMC is possible via enucleation.…”

Introduction and importance It is difficult that doctors other than otorhinolaryngologist/radiologist find early postoperative maxillary cyst (POMC) because it tends to expand gradually with no symptoms over a period of years. Case presentation A 60-year-old Japanese male who had previously undergone a bilateral Caldwell-Luc operation for the treatment of chronic sinusitis, experienced maxillary sinus floor elevation and implant placement. Eleven years after the implant placement, we discovered that the left POMC existed close to dental implants. Fortunately, dental implants still displayed proper osseointegration. Thus, the patient has been successfully treated for POMC, which had not been proper diagnosed before the implantation, by a marsupialization using nasal endoscopy and successfully preserved dental implant. Clinical discussion Because the expanding POMC might result in dental implant failure after several years, we think that marsupialization is useful as a risk management for possible failure of dental implant close to POMC when it had not been found before maxillary sinus floor elevation and insertion of dental implant. Conclusion Doctors should recognize that patients will have the risk of the dental implant failure after several years due to the expanding cyst when early POMC had not been diagnosed and treated properly before the implantation.

“…In a literature analysis of the PubMed database (key words: Marsupialization OR Partsch AND implant; Cyst AND dental implant; Cyst AND endosseus implant; Cyst AND impacted implant; Partsch AND dental implant), only a few case reports about implants impacted in a maxillary cyst can be found. Park et al, in an infected postoperative maxillary cyst, performed cystectomy, implant conservation, decontamination, and bone grafting to fill the defect [20]. Other authors have reported cases of nasopalatine duct cysts impacted in dental implants.…”

“…However, they raised concerns about the possible defect size following enucleation and possible need for bone grafting [11]. Some authors have recommended titanium brushing to debride and mechanically decontaminate implant surfaces and suggested the use of antibiotics and chemical decontamination, although the literature seems inconclusive on this operative protocol [20,[33][34][35]. The authors also decided not to follow through these procedures since the cyst wall seemed intact and presumably absolved a barrier function between implants and cyst cavity, and the surgical access did not allow it.…”

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

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.
