Alveolar atrophy following tooth extraction is a common limitation of rehabilitation with dental implant-borne prosthesis. Direction, rate, and degree of the atrophy shows significant differences in the jaws. Patients frequently present with a knife-edge ridge in the molar and premolar regions of the mandible. Numerous techniques have been described for the horizontal augmentation of the alveolar ridges. Tatum has described ridge splitting to restore bone width prior to implant placement. The aim of our case presentation is to describe a modified approach to ridge splitting. Osteotomies in the recipient site were carried out using a piezoelectric surgical device to mobilize the buccal cortical bone. An autologous bone block harvested from the retromolar region of the mandible was applied as a spacer between the buccal and lingual cortical plates. The block graft was stabilized by osteosynthesis screws. After a 3-month healing period, excellent bone regeneration was observed clinically with perfect ossification in the osteotomy sites. Upon re-entry the augmented area was sufficiently widened to accommodate implants according to the prosthetic plan. Two dental implants were placed in the augmented bone submerged. The submerged of the implants was uneventful. Within the limitations of our studies this novel approach of ridge splitting is a safe and effective method to restore the width of the alveolar ridge.

Prosthetic rehabilitation takes place in the final stage of complete care of a patient born with a cleft lip and palate. Due to the prosthetic rehabilitation, in addition to the restored chewing function, the patient’s voice formation, speech, as well as his social integration and social relations, could improve further. A new denture can also reduce the patient’s mental problems mainly caused by his/her appearance. As a result, at the end of a long, complex care, a child born with a developmental disorder can live a nearly full adult life. In prosthetic rehabilitation, there are several problems, such as difficult occlusion (crossbite, open bite, Angle III class, pillar teeth with different axial positions etc.), narrowed vestibulum caused by the scarring of the area due to the restorative surgeries, or lack of continuity of the alveolar process. In such cases, for the more precise design and construction, the use of CAD/CAM procedure is a great help: dentures can be planned and seen, and thus, fit well from biomechanical, hygienic, and aesthetic perspectives, despite the individual soft tissue conditions.

Implant related biological complications include peri-implant mucositis and peri-implantitis. The main clinical symptoms of peri-implant mucositis is bleeding on gentle probing. In case of peri-implantitis, bleeding on probing and increased probing depth are leading signs. Treatments of peri-implant inflammation are divided into conservative and surgical therapies. The prerequisite for both approaches is the proper professional cleaning of supracrestal implant surfaces. According to the literature, air-abrasive technique is suitable for decontamination of contaminated implant surfaces. Silicate-based powders that are suitable for cleaning supramucosal parts are not soluble in aqueous medium, so their use is not recommended submucosally as the small particles cannot be completely eliminated. Using Varios Combi Pro (NSK/Nakanishi Inc., Shimohinata Kanuma, Japan), water-soluble glycine powder can be applied to the implant surface at an adjustable pressure through a disposable special plastic nozzle. During use, the amount of water cooling can be adjusted. Glycine powder air-abrasive technique cleans the surface of implants more efficiently than cleaning with conventional hand curette without damaging supracrestal implant surfaces. Three patients in this case report underwent clinical and radiological examinations. The peri-implant status was recorded by recording the following parameters: plaque index (PI), calculus index (CI), probing pocket depth (PPD), bleeding on probing (BoP), gingival recession (GR), keratinized mucosa width (KW) and radiological bone loss. Status was also registered at baseline and six months after surgical therapy. Treatment plans of the patients were set up individually, but each treatment involved surgical preparation and air-abrasive debridement with glycine powder with Varios Combi Pro (NSK/Nakanishi Inc., Shimohinata Kanuma, Japan). In two cases, in addition to surgical therapy, free gingival graft (FGG) transplantation was also performed. Peri-implant inflammation was treated successfully in all three cases.

Bisphosphonates (BP) are widely used in the therapy of osteoporosis and bone related metastatic lesions. The two main route of administration of these drugs are: per os and intravenous. The administration of BPs may lead to necrosis of the jaws (medication related osteonecrosis of the jaw, MRONJ). Dental implant success is similar in patients receiving oral BPs and patients not taking BPs. Implant failure and MRONJ is more prevalent in patients receiving intravenous BPs than in patients not receiving iv BP therapy. Dental implant placement in patients receiving BPs require risk assessment for every individual case. Success of implantation and development of MRONJ is influenced by the way of BP administration, the medical condition that determines which type of BPs were prescribed, the duration of BP treatment, and comorbidities that increase the risk of MRONJ. The risk of dental implant placement is low in patients receiving oral BPs for less than four years and have no other comorbidities that might increase the risk of MRONJ. In this article the authors are presenting the oral rehabilitation of a patient with endosseal dental implants who have had hereditary spastic paraplegia and long term oral BP therapy for osteoporosis.

Nowadays, dental implantation is increasingly common intervention in dentistry. With the spread of implantations, implantrelated complications are coming into view. Biological complications include peri-implant mucositis and peri-implantitis. General risk factors for peri-implant inflammation include diseases, such as diabetes mellitus and hyperlipidemia. The aim of this study is to examine the efficiency of blood tests before implantation, as a preventive screening method of implantation and its application in the prevention of peri-implant inflammations. 33 patients’ dental statuses and blood tests were collected. We analysed our data by Microsoft Excel program (Remond, Washington, USA). The patients’ average age was 62,8 (±11). 81,8% of the patients were partial edentulous and 66,7% of partial edentulous patients had periodontal involvement. 21,2% of the observed patients had high blood sugar level, 51,5% of them had elevated blood lipid level. We further examined the association between the prevalence of blood tests’ deviation and the prevalence of periodontal involvement. High blood sugar level and periodontal involvement simultaneously occurred in 6,1% and periodontal involvement with increased inflammatory factors were noticed in 21,2% of the patients. Untreated or not properly treated diabetes mellitus is a risk factor of peri-implant inflammation. Hyperlipidemia has negative effects on the local immune response of peri-implant tissues and osseointegration, which influence the long-term success of the implantation. All of the general risk factors with periodontal involvement increased the risk for peri-implant diseases and therefore we have to make risk analysis and regular controls. The blood-test, according to the Department of Community Dentistry, is a suitable and sufficient method to detect general risk factors before implantation.

More than 1 billion people are estimated to live with some form of disability. These people are considered as a vulnerable group even from a dental point of view, since their compromised functions make the regular oral hygienic routine and also the professional dental management more difficult. Their oral hygiene is poor since the daily oral hygiene routine is compromised and the regular care of these patients with special needs has not been solved in dental practices.
