Minor bone defects of periodontal, traumatic, and endodontic origins can easily be corrected by harvesting the bone intraorally. Also, sinus grafting procedures can be performed using inlay bone blocks from the mandibular symphysis. Mandibular and maxillary bone can be used as a whole block or can be ground into particulate size and grafted. The harvesting techniques should be as gentle as possible, and care should be taken to minimize the extracorporeal time of the graft. The use of intraoral bone donor sites, in comparison with extraoral sites, has several advantages: General anesthesia is not required; there is no need for postoperative hospitalization; and there is less morbidity in the donor sites. Patients must be informed of the benefits and limits of the autogenous bone harvesting in traditional donor sites, along with the benefits and risks in grafting from the alternative sites. A preoperative radiological study of the patient should include panoramic, lateral, and periapical radiographs. Pre- and postoperative antibiotic coverage is indicated with bone harvesting. The only disadvantage in intraoral grafting is the limited quantity of intraoral bone obtainable. While the long-term evaluations are still lacking, the intraoral grafting shows promising short-term results.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"46-51"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20065400","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":"[Therapy of the severely atrophied mandible].","authors":"M Bert","doi":"","DOIUrl":"","url":null,"abstract":"The problems encountered in implant treatment of extensively resorbed mandibles concern poor residual height of the bone and the use of short implants in the least favorable prognosis, excessive corticalization of the bone making drilling difficult, poor vascularity of the implant site, and mechanical constraints sustained by implants bearing high prosthesis. This paper addresses these problems and suggests solutions, using author's own experience and the findings of other clinicians, published in professional literature. To solve poor vascularity of the implant site, the paper suggests preliminary stimulation of the bone prior to implant placement. New drilling steps are described, calling for disposable drills not only in the initial phase but in the subsequent drilling as well. Using a new drill for each surgical procedure provides the optimal sharpness, thereby decreasing the temperature generated at the site, which must not exceed the limit of 47 degrees C. To improve short implant performance, the use of wider diameter implants with tapping insertion is suggested for initial stabilization, along with avoidance of premature utilization of the implant. An unfavorable ratio between the prosthesis and the implant may cause fractures either in the implant or the prosthesis. To avoid these fractures, utilization of wider diameter implants, decrease of the cantilever size, and gradual utilization of the implants are suggested.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"52-5"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20065401","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":"[Teamwork and communication in implantology: dentist--technician--implant surgeon].","authors":"M Wolf","doi":"","DOIUrl":"","url":null,"abstract":"The importance of presurgical communication and cooperation between the restorative dentist, dental technician, and the implant surgeon is well recognized in modern implantology. The predictable outcome of function and aesthetics of intraoral rehabilitation can and must be determined and controlled prior to the surgical procedure, with the entire restorative team cooperating from treatment planning to the completion of the prosthetic procedure. The paper reviews the assessment of bone height and width by intraoral measurements and preexisting formulae, the use of radiographs, model analysis, and implant placement on model. A particular implant system (Steri-Oss, Yorba Linda, CA) is used. The rationale for angulating implants, originating from the shape of the bone is discussed. The optimal implant position can be determined only by a set-up; the drill jig copies the information from the articulator to the intraoral arch and provides the surgeon with a maximum assurance of the outcome. The try-in and changes are discussed, followed by the actual surgical procedure. After the healing period, use of the jig can assist in implant recovery. The wax-up can be used to maintain silicone vestibular walls and help to model the gold frame of the laboratory work. The emphasis is placed upon the cooperative teamwork of the restorative team, especially the contributions of the laboratory and other technology to the functionally and aesthetically successful final result.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"12-5"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20066420","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":"[Posterior implant-supported single crowns: a new treatment approach].","authors":"M F Bender","doi":"","DOIUrl":"","url":null,"abstract":"Up to the present time, the discussions of single crown restorations with dental implants have been focused primarily on the anterior maxilla or mandible. This clinical case presentation illustrates that it is possible to reconstruct the posterior mandible, and, for the first time, even the subantral augmented maxilla after sinus elevation, with single crowns supported by implants. The presented treatment philosophy imitates natural human dentition. After a single tooth loss, an implant is placed immediately in order to provide functional stimulation of the bone, thereby maintaining the activity of the osteoblasts and keeping the alveole bone is sound condition due to the natural function. After extensive bone augmentation, reconstruction, proper healing time, and precise prosthetic planning of the optimal location of the crowns, implants were placed accordingly and later restored with single crowns in the size of premolars. According to the natural dentition, the author placed one implant per molar root, ie, one implant each for the mesial and distal root of the first molar and possibly the mesial root of the second molar. In all the cases restored, the crown/root ratio was smaller than one. The size of the crown is designed in such a way that the masticatory forces are transmitted axially and vertically via crown into the implant. In 16 clinical cases, none of the 96 single crowns and implants (28 of these in the augmented subantral region of the maxilla), have been lost during 6 months to 3 years of use.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"65-9"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20066770","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}

[Esthetic and prosthetic procedures in single-tooth replacement]. [单牙置换术的美学和修复程序]。

{"title":"[Esthetic and prosthetic procedures in single-tooth replacement].","authors":"G L de Lange","doi":"","DOIUrl":"","url":null,"abstract":"Loss of anterior maxillary teeth always results in bone resorption and loss of interdental papillae, and the resorption makes a single tooth replacement by a dental implant very difficult. When infections have been present and the patient's history shows previous surgery at the apex of the root, bone destruction is substantial, which results in an increased resorption defect, thereby further increasing the aesthetic and prosthetic problems. This paper describes the steps necessary for implant surgery and the prosthetics; a brief summary is provided. The quality and quantity of bone, along with the space available between the adjacent teeth, are the basic factors in treatment planning and determine the type of implant to be used. Some resorption and bone defects are usually present after a tooth extraction, and bone regeneration procedures can be performed either before or simultaneously with the implant placement, with numerous flap designs available. Soft tissue augmentation can be achieved by taking a connective tissue graft from the palatal side. Antirotational devices (eg, hex lock abutments) are necessary for all implants in single tooth replacement. Screw-retained abutments can be used in posterior areas and in angled positions in facial areas as well. With proper single tooth implant position, cementation of laboratory fabricated crowns can be considered.","PeriodicalId":79498,"journal":{"name":"International journal of dental symposia","volume":"2 1","pages":"70-6"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20066771","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}
