Objective:This study used published studies to assess the survival rate of dental implants placed in patients with bone dysplasia of the maxillofacial region.Material and methods:An electronic search without a specified date range was performed using the MEDLINE,PubMed,EMBASE,Web of Science,and Cochrane databases.No gender or age restrictions were applied.Results:Eighteen publications were found that met the study’s criteria,reporting data on 18 patients with bone dysplasia including cleidocranial dysplasia(CDD),fibrous dysplasia(FD),florid cemento-osseous dysplasia(FCOD),and odonto-maxillary segmental dysplasia(SOMD),who received a total of 130 implants,an average of 7.2 implants/patient(range 1 to 16).The mean age of the patients was 36.7 years(range 15 to 70 years).For implants placed in bone dysplasia,the survival rates were 100% for patients with CDD(n=8),FD(n=5),SOMD(n=2),FCOD with implants inserted far from the lesions(n=2)and 0% for dental implants inserted within FCOD(n=1).The mean follow-up was 38.2 months(min 6,max 60).Conclusions:Dental implants placed in patients with dysplastic bone lesions show high survival rates,similar to those in the general population for CDD,FD,and SOMD.For FCOD,the failure rate was 100%. 展开更多

Dental implants with a reduced diameter can be placed in regions that lack adequate bone volume enabling functional and aesthetic oral rehabilitation without the complicated bone augmentation procedures.This article describes surgical and prosthetic procedures used in oral rehabilitation using Straumann R one-piece Mini Implants(2.4-mm diameter with Optiloc R prosthetic connection system)in two fully edentulous women aged 57 and 74.Both patients presented with severe ridge resorption.Ten one-piece mini dental implants(six on maxillary arch and four on mandibular arch)were placed in each patient to support new complete overdentures.Both patients were delighted with the results and regained their social lives.In addition,stabilized dentures allowed the patients to regain fundamental functions of the mouth:chewing and verbal(speech)and non-verbal(smiling)communication without the fear or difficulty experienced while wearing dentures that can move.In conclusion,mini implants offer an efficient,economical,and less invasive solution,especially for edentulous patients with atrophic bone structure or who cannot undergo complex surgical procedures. 展开更多

Osteoradionecrosis(ORN),a pathological condition characterized by a nonvital bone occurring in the site of radiation injury,is one of the significant risks following extraction of highly impacted third molar teeth in patients treated with head&neck radiotherapy for oral cancer.Therefore,the surgery’s meticulous planning is essential to avoid such complications.This case report describes a 63-year-old male patient diagnosed with an impacted lower third molar(tooth#38)with concurrent basal cell carcinoma of the right ear and squamous cell carcinoma of the right vocal cord treated with radiotherapy.Taking into account the patient’s health status,a minimally invasive osteotomy and a corono-radicular separation procedure were performed.This procedure allowed us to reduce the risk of mandibular ORN.Three years later,the healing was complete,and the situation was stable. 展开更多

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. 展开更多
