Long-Term Implant Survivability of an Implant Having Direct Contact with Cementum-Like Tissue in a Preexisting Mandibular Intraosseous Lesion with a 16-Year Longitudinal Follow-up

Cemento‐osseous dysplasia (COD) is defined as a condition in which normal bone is replaced by fibrous connective tissue and cementum‐like deposits. It is generally asymptomatic and occurs mostly in female patients. Radiologically, it appears as an opaque, lobulated mass. When facing such lesions, it is advised to avoid performing any surgical procedures due to the decreased vascularization and healing potential. The main reported complications being poor healing, sequestrum formation, risk of infection, and fracture of the jaw. Treating posterior mandibular edentulism in presence of a COD can be a challenging situation especially when the patient requires an implant‐supported fixed rehabilitation. The aim of this paper is to describe a three‐stage modified protocol for implant placement in a compromised site presenting a focal cemento‐osseous dysplasia.

“…In 6 publications dealing with 6 cases, the implants were placed within or outside the lesion; [11,12,15,[17][18][19] only 3 cases among the 6 described were successfully integrated. [12,18,19] Gerlach et al [15] described implant failures in a FLCOD, but the mandible was also affected by a cemento-ossifying fibroma (COF). Oliveira et al, [17] as well as Shin et al, [11] have also reported cases of implants failures in FLCOD manifested by the loose implant, swelling, and pain.…”

“…Oliveira et al, [17] as well as Shin et al, [11] have also reported cases of implants failures in FLCOD manifested by the loose implant, swelling, and pain. Park et al, [12] on the other hand, have demonstrated the possibility of long-term implant survivability in FCOD with implant sta-bility at 15 years. He explained it by the fact that the screw was placed within a mature lesion (late stage), increasing bone-implant contact (BIC).…”

We present a 45-year-old black woman diagnosed with a florid cemento-osseous dysplasia (FCOD) affecting the right lower quadrant and the anterior mandibular region. The patient requested dental implants to rehabilitate the edentulous central lower incisors area (teeth # 31 and # 41) corresponding to a periapical cemento-osseous dysplasia (PCOD). Successful osseointegration of the two implants was obtained using a two-step procedure in order to limit the risk of complications associated with implant placement. Follow-up at one year showed no recurrence and good implant stability. Due to the abnormal quality of the bone in cemento-osseous dysplasia (COD), implant placement is generally avoided, and no other case reports have been reported in the literature in patients affected by PCOD. The present case suggests that in an appropriate clinical setting, implant placement may be a successful procedure.

Florid cemento-osseous dysplasia (FCOD) is a rare benign fibro-osseous lesion which affects multiple quadrants and predominantly the mandible. This case report presents a successful implant placement with 8-year of follow-up in a 44-yearold woman asking for a fixed restoration in mandibular right posterior edentulous area. Radiographic images showed lobular, irregularly shaped radiopacities and radiolucencies almost symmetrically observed in the premolar-molar area of the right and left regions of the mandible. The findings of Xray images were attributable to FCOD. Minimally invasive two-stage surgery with strict infection control was followed to place two implants in lower right posterior region. The implants demonstrated clinically rigid fixation and restored successfully after 6 months. A direct functional connection between dysplastic bone and the implant load bearing surface was evidenced by the lack of symptoms, and the lack of soft tissues inflammation or peri-implant bone loss up to 8 years follow-up.
