{"title":"[The maxillary challenge in oral implantology].","authors":"J E Bori","doi":"","DOIUrl":"","url":null,"abstract":"The implant recipient site may at times be inadequate or absent due to the presence of an oro-antral fistula, and procedures have to be implemented to remove the fistula, debride, and bone graft the implant site. This presentation and paper address several innovative procedures and their indications. Four sinus augmentation modalities and a \"T.L.C. Window Approach\" are described and illustrated. The first three modalities are classified as Sinus Augmentation No. 6. The debridement procedure is outlined in 4 steps: Deepithelialization of the soft tissue aspect of the oro-antral fistula; a circumferential incision; debridement and suture of the fistulous tract; and augmentation of the sinus. The extent of the osseous oro-antral fistulae involvement is classified as Types S, M, and L (small, medium, and large), and the measurements are indicated. The fourth modality is titled Sinus Augmentation No. 7, and it is concerned with the treatment of large sinus, further underlined by a severely lingualized \"available bone\" trajectory. To correct this type of case, the author suggests the Sinus Augmentation No. 7 modality, which, by definition, is the extemporaneous correction of the aforementioned deficiency, using a sinus augmentation (SA.4 modality) coupled to an autogenous inlay-onlay bone graft (endchondral or membranous), bearing root form implants and osteosynthesized to the palatal osseous wall of the S.4 type sinus. The \"T.L.C. Window Approach\" is used when a foreign body is present in the antral area and has to be removed to avoid the possibility of infection or impaired osteal drainage at the same time a sinus augmentation is performed.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"22-7"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20065395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Preoperative and surgical protocols for better implant integration].","authors":"G Takács","doi":"","DOIUrl":"","url":null,"abstract":"In implant placement, different bone densities require different implant types in order to achieve maximum stability. Therefore, careful preoperative planning is essential to diagnose and/or augment the bone, to select the correct size and type of implant for each individual case, and to establish the appropriate surgical protocol. This paper and presentation discuss the essentials for establishing such protocol, ie, the quality and quantity of bone, type and size of implants, surgery, progressive loading, and shifting of the mastication forces. Serious errors in planning first appear as short-term failures, and they indicate inadequacy in osseointegration in the healing phase or overloading caused by the superstructure. Less grave errors occur later as long-term failures, due to the width, depth, and density of the bone and the angulation of the implant. Appropriate components have to be used for different types of bone: Uncoated screws are the best solution for D1 and D2 types of bone; coated screws should be used in the presinus area and after nerve transpositioning. Cylindrical implants are best suited for subantral augmentation, using a narrow drill; the bone bed is progressively widened by a conic osteotome, and the technique provides a good stability. Free gingival transplant is indicated in cases with insufficient keratinized gingiva. Masticatory overloading can be avoided by reducing the occlusal table, decreasing cusp inclination, and anteriorizing the upper mastication areas.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"28-31"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20065396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Subantral graft: clinical application of the biological principles osseoinduction in the treatment of posterior maxillary atrophy].","authors":"V S Lamberti","doi":"","DOIUrl":"","url":null,"abstract":"Severe resorption in the posterior maxilla following the loss of natural teeth is frequently associated with severe pneumatization of the maxillary sinus. This condition reduces the possibility of using implants in the subantral maxilla to surgical and prosthetic limits that cannot be resolved by simple techniques. For these cases, maxillary sinus elevation surgery and subantral grafting are required in order to increase this segment of the maxilla. The availability of new biomaterials has increased the possibilities of performing these techniques by reducing the amount of autogenous bone that must be harvested. Osteogenesis, osteoinduction, osteoconduction, osteotrophism, and osteophilia are the biologic mechanisms involved in the formation of new bone. Presence of these mechanisms permit augmentation of the subantral osseous band and bone to dimensions needed for implant placement. Conductive biomaterials permit bone neoformation to begin at the margins of the defect and advance towards the center. In a clinical study of 42 months, 228 implants (Steri-Oss, Yorba Linda, CA were placed; 180 of them are loaded and functional. The threaded design, HA-coating, hex lock head, and a resorbable membrane promote osseointegration and longevity. A subantral graft was placed in the space created after release and elevation of the sinus mucosa. The histologic evidence and the supportive clinical and radiologic findings clearly demonstrate consolidation and integration of the graft and the implant.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"56-9"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20065402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

[Keys to success in implant osseointegration]. 种植体骨整合成功的关键。

{"title":"[Keys to success in implant osseointegration].","authors":"A P Saadoun, M Le Gall","doi":"","DOIUrl":"","url":null,"abstract":"The potential utilization of osseointegrated implants should be considered in every treatment planning along with the knowledge of specialists-periodontists, implantologists, and prosthodontists. Prosthetic objectives of function, aesthetics, and maintenance should guide the implant procedure. The purpose of this article is to emphasize how periodontal procedures enhance the cosmetic result and ensure a successful long-term restoration. The search for the best position and orientation of the implant in the bone is guided by the prosthetic phase. Periodontal treatment or extraction of the residual teeth is performed before any placement of implants. Absence of infection and adequate apical bone are necessary to insure primary stabilization. Graft and membrane procedures are done prior to or simultaneously with implant placement. When placed immediately upon extraction, the long axis of the implant should line up with the incisal edge of the adjacent teeth. The compass technique can be performed when the opposite arch of the implantation is edentulous or partially edentulous. The healing abutment serves as a matrix for the gingiva to heal and must replicate the cervical diameter of the tooth. The 6-year results of a previous 5-year study have reconfirmed the results: Quality of bone is the determining factor in success rates; the deeper the bone, the lower the failure rate; a failure rate is most likely to take place during the first year after placement; a higher success rate is found in the mandible; and a higher success rate is found with HA-coated implants.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"6-11"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20066768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Immediate placement of an implant after extraction].","authors":"P Missika","doi":"","DOIUrl":"","url":null,"abstract":"The immediate placement of an implant is not only possible but in some clinical situations advisable, with each case individually assessed and the time of placement determined by the clinician. In such cases, the immediate implant placement provides a considerable number of advantages over the traditionally established placement. When using the traditional procedure, a 3 to 6-month healing period is necessary before an implant can be placed and another 3 to 6 months before prosthodontic restoration. An immediate placement combines postextraction healing phase with the integration phase, reducing the total healing period by one-half. An immediate placement prevents the bone resorption in the alveolar crest, thereby eliminating an aesthelic problem, and it permits the bone to regenerate in the alveolar space around the implant. It permits a precise placement with better resistance to occlusal and lateral forces. It avoids drilling of the cortical bone and conserves good tissue thickness and the attached gingiva, thereby providing a better aesthetic result. Finally, by eliminating the waiting period, it provides a significant psychological and functional advantage. In recent years, numerous dental surgeons have placed implants immediately after the extraction, and the technique has now become a well accepted restorative technique.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"42-5"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20065399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
