Dental implants in a patient with a large idiopathic osteosclerosis of maxilla

Background : Numerous clinical studies have stated that the long- term survival of dental implants is more than 96%. A 21- year old healthy male patient referred at the Department of Oral and Maxillofacial surgery for a surgical removal of impact both upper right premolars before implant placement. The patient was followed from 2005 by his dentist and orthodontist who noticed that permanent dentition (teeth 13, 14, 15) had difficulties in erupting. This condition was caused by a large sclerotic, radiopaque bone abnormality that was asymptomatic and well delineated from surrounding normal bone. Aim/Hypothesis : There are different factors related to implant failures that can be divided in patient related factors, iatrogenic factors and dental implants factors. The aim of this presentation is to describe some important and simple steps that can improve early and long- term survival of dental implants in a patient with a large idiopathic osteosclerosis. Material and Methods : On initial clinical examination the patient presented with normal toothless canine and premolar regions. A CBCT analysis confirmed a large sclerotic area in right maxilla that impact the premolar teeth without displacement of adjacent teeth or bone expansion. In general anaesthesia bone biopsy was taken and tooth 14 was removed. Tooth 15 was left because its removal would result in a large bone defect. The histopathology examination showed highly dens mature lamellar bone tissues. A diagnose of idiopathic osteosclerosis was made. After 2 months of uneventful healing 3 implants (Astra tech ® , Syrona Dentsplay, Germany) were inserted using the high dens bone protocol and the one- stage healing abutments were placed. The implants were chosen because of the good drilling protocol for dens bone and microthreads in the neck that can help to reduce bone stress and marginal bone loss. Also we used sterile saline that was cooled to 5°C for external irrigation to reduce heat generation and prevent osseous necrosis. Six months after the uneventful healing period an individual fixed screw- retained CAD- CAM zirconia oxide ceramic hybrid abutment- bridge was fabricated. Results : The one year follow- up clinically and radiographically showed good and stabile results of implantoprosthetic rehabilitation both in function and aesthetics. Also patient satisfaction was excellent. Conclusions and Clinical Implications : Choice of implant design, surgical protocol and control of heat generation are important factors that we can influence for successful osseointegration of dental implants. These factors are very important in situations of poor bone quality like in idiopathic osteosclerosis. It is very important to rule out other pathological bone entities like diffuse sclerosing osteomyelitis, osteoma and compact osteoma to plan adequate therapy and implantoprosthetic rehabilitation.
