Splinting osseointegrated implants and natural teeth in rehabilitation of partially edentulous patients. Part I: laboratory and clinical studies.

A significant clinical consideration in the restoration of partial edentulism with implant and tooth-supported prostheses is whether implants and natural teeth abutments should be splinted, and if so, in what manner. This article presents a review of laboratory and clinical studies related to splinting. Stress analysis studies reveal high stress concentration around the implant neck when rigidly connected to teeth. This was not borne out in in vivo studies in short-span bridges. While stress absorbing elements have been advocated to redistribute and reduce stress concentration away from the implant neck where bone resorption is often seen, finite element analysis and photo-elastic studies demonstrate that such stress absorbing elements may be effective only when their resiliency is in the same order of magnitude as the periodontal ligament. Clinical studies reporting life table statistics in combined implant and tooth restorations do not show adverse effects of splinting teeth to implants. These studies, however, are mostly short-term reports on survival with results that are as yet inconclusive. The issue of connecting with rigid or non-rigid connectors remains unresolved with a growing body of information favouring retrievable short-span rigid connection to non-mobile teeth. Root intrusion is a potential clinical hazard of non-rigid connection.

Reactive force distributions for teeth when loaded singly and when used as fixed partial denture abutments.

1. A finite element model was devised to examine mechanical responses of the periodontium to loads applied to the model in vertical, oblique, and horizontal directions for an individual tooth having varied alveolar levels, splinted teeth, and a cantilever type of fixed partial denture. 2. Forces applied to the teeth are balanced by stresses generated within the periodontal membrane and alveolar bone. 3. It was substantiated that the teeth were evolved to carry axial types of loads, since stresses on the periodontium were smaller than those obtained for oblique or horizontal types of loads. Axial types of loads produce compressive stresses on the periodontium; oblique or horizontal types of loads produce zones of compressive and tensile stresses. 4. Mechanically, splinting teeth is a desirable procedure. 5. A cantilever type of fixed partial denture should have at least two abutments. It should not be used to replace more than one tooth.

[Reduction of bony periodontal pockets with hydroxyapatite].

If you can't reduce a periodontal bone defect of more than 6 mm with a conservative therapy you can open up the pocket with a marginal incision. The granulation tissue must be removed carefully, open up the surrounding spongiosa and clean the tooth from calculus. HA-Granula is filled into the pocket but don't overfill it. Use Matrix-sutures to sew the wound very dense against saliva. A final splint stabilizes the tooth.

Replantation of avulsed primary anterior teeth: treatment and limitations.

In addition to the successful replantation of avulsed permanent teeth, the replantation of primary anterior teeth may also be indicated. The decision is based on age and stage of tooth development, development of dentition, storage of the avulsed tooth and the way it is transported to the treatment site, the appropriate in vitro treatment of the tooth before reinsertion, and the willingness of the child to cooperate. A method involving retrograde filling of the primary tooth root with calcium hydroxide after resecting the root apex has proved successful. Other commercially available root filling materials and pins are not indicated. Calcium hydroxide allows the tooth to heal in place without reaction and prevents the development of apical periodontitis. As regards any surgical intervention, the attending dentist in this case has to weigh the benefits against the risks.

Healing of 208 intra-alveolar root fractures in patients aged 7-17 years.

This retrospective study consisted of 208 root-fractured, 168 splinted and 40 not splinted incisors in young individuals (aged 7-17 years) treated in the period 1959-1973 at the Pedodontic Department, Eastman Institute, Stockholm. Clinical and radiographic analyses showed that 69 teeth (33%) had developed hard tissue (fusion) healing of fragments. Interposition of periodontal ligament (PDL) and bone between the fragments was found in 17 teeth (8%). Interposition of PDL alone was found in 74 teeth (36%). Finally, non-healing with pulp necrosis and inflammatory changes between fragments was seen in 48 teeth (23%). Various clinical factors were analyzed for their relationship to the healing outcome with respect to healing/no healing and type of healing (hard tissue versus interposition of bone and/or PDL). Immature root and positive pulp sensitivity at time of injury was found to be significantly related to both pulp healing and hard tissue repair of the fracture. The same applied to concussion or subluxation of the coronal fragment compared to luxation with displacement (extrusive or lateral luxation). This relation was also represented by the variable millimeter diastasis between fragments before and after repositioning. Repositioning appeared to enhance the likelihood of both pulp healing and hard tissue repair. A positive effect of splinting, splinting methods (cap splints or orthodontic bands with an arch wire) or splinting periods could not be demonstrated on either pulp healing or type of healing (hard tissue versus interposition of bone and/or PDL). In conclusion, the findings from this retrospective study have cast doubts on the efficacy of long-term splinting and the types of splint used for root fracture healing. It is suggested that the role of splinting and splinting methods be examined in further studies.

Tooth loss in 1535 treated periodontal patients.

Of 1535 treated recall patients surveyed over an average time of 12.9 years since treatment was completed, 1371 had lost no teeth from periodontal disease. The total number of teeth lost was 444, with the average tooth loss for the 1535 patients being 0.29. In the three full arch splinted cases, the loss rate was 14.67 teeth per patient. Patients treated without any excisional or flap surgical procedures made up 26.5% of those surveyed, whereas 73.5% had required various surgical procedures. No attempt was made to compare different pocket therapy procedures. Although many patients developed recurrent periodontal problems during recall, only 15.9% of the 1535 patients required surgical retreatment. Teeth that were originally given a doubtful prognosis often were responsible for recurrent problems and sometimes required extraction.

Impact of a periodontal course on oral hygiene and gingival health among senior dental students.

This survey attempted to determine the impact of the periodontal course on oral hygiene and gingival health among 50 senior dental students. The course included the following: patient motivation, instruction in oral hygiene procedures and plaque control, scaling and curettage, temporary splinting and occlusal adjustment. Without advance notice, plaque deposits were scored using the Plaque Index and gingival health was determined using the Gingival Index. The results were collected at the beginning and at the end of the periodontal course (about 2 months). The results were analyzed using the paired t-test. No improvement of either oral hygiene or gingival health was noted at the end of the periodontal course. It seems that even some dental students, who should know the direct relationship between bacterial plaque and periodontal diseases and should be better motivated than the average patient, failed to demonstrate effective oral hygiene. It is difficult to expert an improvement of patient oral hygiene, when the patients have been motivated by students who are unable to perform satisfactory personal oral hygiene themselves. It is suggested that a greater emphasis be placed on patient motivation and instruction in oral hygiene throughout the dental curriculum.
