Objectives: The purpose of this study was to evaluate horizontal zero-dimensional changes of the buccal alveolar plate using cone-beam CT (CBCT) following maxillary premolar single immediate implant placement into fresh extraction socket. A novel intra-socket grafting technique (IGT) was used for placing graft material into the implant–socket gap to minimise the resorptive process. Methods: A 58-year-old woman in good general health required extraction of a maxillary first premolar (1.4) due to fracture, with extraction and immediate implant placement. Her soft tissues were healthy with good thickness and normal periodontium. Extraction involved minimal trauma to the bone and soft tissue. The osteotomy was prepared towards the palatal plate. A decision was made to fill the gap between the internal surface of the labial socket wall and the implant surface before installing the implant by IGT, with bovine-derived particulate grafting material (Bio-OssTM) to support the buccal bony contour. The TE-SLA 4 implant (diameter 4.8 mm, length 10mm) was inserted in the implant bed in a slightly palatal position and primary stability was achieved. The implant shoulder was placed about 3mm apical of the gingival margin. A resorbable collagen membrane (Bio-GideTM) was applied and sutured. Four months after placement, a screw-retained provisional crown was attached to the implant, which was then restored with a cement-retained metal-ceramic crown. CBCT was performed six months after implant surgery and compared with pre-extraction images using imaging software (OnDemand3DTM) to superimpose scan data for evaluation of crestal preservation. Results: Healing was uneventful and the implant site was clinically stable and inflammation-free throughout follow-up. The aesthetic outcome was stable and pleasing. Periapical radiography at the one-year showed a well-integrated implant with stable crestal bone level. CBCT scans taken six months after surgery showed good integration of the graft in the bed and the implant surface, and complete radiographic healing. The scan data revealed preservation of buccal alveolar bone thickness in coronal, middle and apical points after six months, and that using bovine derived-xenograft material to fill the implant–alveolar gap preserved buccal alveolar thickness on the coronal aspect and at the midfacial level, where the buccal width plate is often constricted. Conclusion: Within the limitation of this study, the IGT procedure was associated with horizontal bone stability of the buccal alveolar plate following maxillary premolar single immediate implant placement. The case met the following criteria: i) intact buccal bony plate before and after tooth extraction with an intact periodontium; ii) flapless immediate implant placement procedure; iii) grafting of the implant–socket gap using a bovine-derived bone substitute; iv) placement of the implant towards the palatine bone wall, with adequate primary stability. When these requirements are met, immediate implant placement in fresh extraction socket provides predictable aesthetic outcomes and stable peri-implant tissues. CBCT data clearly demonstrated the preservation of buccal alveolar bone.

Not long until the EuroPerio 8 Congress in London starts. And Osteology will also be there with the latest news about the Osteology Symposium 2016 in Monaco, new funding possibilities for researchers - and a sweet surprise... The EuroPerio Congress has established itself as one of the worlds leading conference in periodontology and implant dentistry, and has become a triennial fixture on the meetings calendar. The 2015 meeting takes place in London, and is hosted by the British Society of Periodontology for the European Federation of Periodontology. Up to 10000 delegates are expected. The organizers have put together an impressive program with to 6 sessions will run in parallel throughout the meeting. The Osteology Foundation will be present at the congress with its own booth in the exhibiton area, presenting the latest news about the preparations of the Osteology Symposium 2016 in Monaco, new funding possibilities for researchers that will be available soon - and a sweet surprise...

Objectives: Tooth agenesis is one of the most prevalent congenital craniofacial disorders. The term oligodontia is generally used for agenesis of six or more teeth, and it can be related to a syndrome or present as an isolated condition. The prevalence in permanent dentition is 0.14%. This article reports a case of oral rehabilitation using implants and hard tissue regeneration in a patient with agenesis of 15 permanent teeth and following orthodontics. Methods: A 23-year-old Caucasian man, was referred to the Department of Periodontology and Oral Implantology at Ghent University Hospital. His chief complaints were functional and aesthetic, related to oligodontia. Orthodontic treatment was initiated at the age of 15 in preparation for future implant placement. In addition, the upper third molars were transplanted to positions 35 and 45. After orthodontic treatment, a cone beam computerised tomography (CBCT) scan was taken for surgical treatment planning, including implant placement. Concave and knifed-edged bone in the upper jaw and the limited bone quality and quantity of the lower jaw indicated the need for bone augmentation. The materials selected were seven Astra EVä/® implants, and Bio-Ossä/® and Bio-Guideä/® for the hard tissue regeneration. Second-stage surgery for the low bone quality and hard tissue regeneration was scheduled for 6 months after placement. Two weeks after this minimally invasive surgery, prosthodontic therapy was initiated. Open-tray impressions were made to manufacture provisional, screw-retained crowns. The shape of the provisional restorations was adjusted by adding composite, putting pressure on the mucosa and optimising the pink aesthetics. Results: The treatment included orthodontic therapy, tooth transplantation, a fixed partial denture in the anterior mandible and seven single implants. Implant placement was via flap surgery and simultaneous guided bone regeneration (GBR) in the upper jaw. Reduced height, width and quality of alveolar bone are common in patients with congenitally missing teeth are; to deal with this, and to restore the buccal contour, GBR was deemed necessary. Implants were covered after 6 months and provisional restorations were made on teeth and implants. The patients is currently functioning with the provisional restorations, which have had a profound impact on his self-esteem. Permanent restorations will be placed after another 6 months. To date, the buccal contour of the implant sites has shown limited resorption. Conclusions: Treatment of oligodontia patients with dental implants is challenging because of the reduced height, width and quality of alveolar bone. This report demonstrated that a proper multidisciplinary treatment plan offers a predictable solution for complex cases. The choice of biomaterials significantly impacts on the final aesthetic outcome.
