Following a rigid plan and treatment protocol will maximize dental implant success--Part I.

A properly established protocol ensures success when providing implant therapy for the dental patient. The basis for achieving doctor/patient objectives emphasizes esthetics, phonetics, function, longevity and maintainability. Too often patients are presented with completed prosthetics without prior consideration of their expectations. This article identifies and describes each phase of pre- and post-surgical planning and the role of each implant team member. The goal of this article is to illustrate the value of utilizing specific treatment protocols to guide the restoring dentist, surgeon, technician and patient toward predictable results while minimizing uncertainties.

[Electron microscopic examination of the surface morphology of dental implants].

The surface morphology of implants plays a considerable role in their long-term stability. The authors summarise the results of their research of the surface morphology of dental implants. They describe in detail the methods of manufacturing the surface and their analysis. In their study the SEM was used for surface analysis.

[Insertion of dental implants in the Highmore antrum. Improvement of the maxillary sinus base by bone meal and Tissucol].

After five years of experience and good results, the A. introduces a new method for inserting dental implants into the upper jaw. In the majority of cases fails the insertion of the implant in this area, because of the thinness of the bony ring between the alveolar crest and the base of the sinus, resulting in defective fixation. The fixation of the implant is made, after the elevation of the mucosa of the alveolar recess (whether normal or pathological) with a mixture of bone meal and "Tissucol". This compound (paté) wraps the implant, previously set in place by the dentist. In cases of maxillary sinus surgery, the A. recommends, once the mucosa has been treated, to fill the alveolar recess with this paste moulded as a sloping surface running from the outer wall of the sinus toward the floor of the nose, both cavities communicating through the due counter-opening.

Intraindividual comparative animal study of alpha- and beta-tricalcium phosphate degradation in conjunction with simultaneous insertion of dental implants.

An intraindividual comparative study of proximal tibial marrow defects in nine adult Goettinger miniature pigs (GMPs) was undertaken. The left side of the defect was filled with granular beta-tricalcium phosphate (TCP) ceramic ad modum Cerasorb, and the right side was filled with granular alpha-TCP ceramic ad modum Biobase alpha pore. Simultaneously, dental screw implants were inserted in each ceramic and fixed within the orthotopically replanted corticalis lids. Control defects were made in two other animals. The survival period ranged from 4 to 86 weeks (control study, 16 and 20 weeks). The reorganization and degree of bone regeneration, dynamics of ceramic degradation, and remodeling characteristics of the bone regenerate referring to osseo-integration of the dental implants were examined histomorphologically in nondecalcified specimens. The results reveal that both ceramic types were osteoconductive exclusively. Centripetally oriented angiogene bone regeneration occurred at the margins of the circular defects. Ceramic degradation was performed hydrolytically and within cells. Furthermore, it was demonstrated that decomposition of the intratrabecularly integrated ceramic residues underlies a dynamic process of degradation. Within 86 weeks, nearly 80% to 90% of the larger alpha-TCP granules, and nearly 90% to 95% of the beta-TCP granules were degraded. At this time, especially for the alpha-TCP modification, ceramic microparticles were found in the marrow, either unbound or within polynuclear macrophages. The predictable degradation of both ceramic types provides an early functional adaptation of bone regenerates and facilitates a biofunctional, anisotropic orientation of the neotrabeculae without delay. It is concluded that because of the initially pronounced accumulation of macrophages, dental implants should not be inserted simultaneously with ceramic, but after further progress of ceramic degradation (5 to 6 months after TCP implantation).

Osseointegrated dental implants as alternative therapy to bridge construction or orthodontics in young patients: seven years of clinical experience.

Young patients often require fixed bridgework or orthodontic therapy in cases of traumatic tooth loss or congenitally missing teeth. Dental implants represent an alternative to the more conventional treatment methods. We report positive experience over a seven-year period with 42 titanium Ha-Ti implants in 34 patients aged 9 to 18 years. Fourteen implants were placed into prepared tooth sockets immediately after traumatic luxation of anterior teeth in 12 patients aged 9 to 18 years (median age 16). An additional 22 patients (median age 15.5, range 11 to 18) also received implants (N = 28), but these were placed only after healing of extraction sites, or as substitutes for congenitally missing teeth. Implants remained in situ for an average of 7.7 months before loading. During the healing period, three implants were lost due to additional trauma and one became infected. The 38 remaining implants osseointegrated and since have been loaded for five to 79 months in successful function. There was no difference between immediate and delayed implants in clinical success. These experiences demonstrate that appropriate, versatile, osseointegrated implants can provide a successful treatment method for young patients, without damaging adjacent teeth.

A clinical retrospective evaluation of FA/HA coated (Biocomp) dental implants. Results after 1 year.

In this retrospective clinical evaluation, the performance of loaded titanium implants with a bilayer bioactive surface coating of the relatively reactive hydroxylapatite (HA, outer layer) and the more stable fluorapatite (FA, inner layer) was evaluated. 98 consecutive patients were included in the study for a total of 354 implants, loaded by overdentures, fixed partial dentures and single tooth replacements. Statistical analyses revealed a cumulative probability of implant survival on a per patient basis of 94.5% (s.e. 2.7%), one year after implant installation. On implants that were lost parts of the bilayer FA/HA coating had vanished as a result of primary or secondary infection and subsequently epithelial down growth. Most complications were associated with implants placed in the maxilla. Periotest values (PTV) were generally high, indicating adequate osseointegration. The PTV's were statistically significantly less favorable in implants placed in the maxilla. The most favorable PTV's and gingival index scores were found around implants servicing overdentures. Marginal bone loss averaged approximately 2mm during the observation period. The amount of marginal bone loss corresponded with the distance from the neck of the implant to the first thread of the implant's cervical screw-section. It is concluded that, during the relatively short observation period, the FA/HA coated implants function adequately. However, in the absence of a direct implant-to-bone contact preceding implant loss, part of the FA/HA coating on the titanium implants generally dissolves.

[Combined periodontal treatment with dental implants].

Implant treatment of partial edentulous periodontal compromised patients have led to a change in indication and therapy. After an adequate periodontal treatment for most of the patients there are no obstructions for implant treatment. However untreated periodontal disease and refractory periodontitis patients are at risk for complications. The diagnosis, treatment planning, treatment and maintenance of periodontal compromised patients need a multidisciplinary approach. A regular and tight maintenance program is essential to keep the periodontal and peri-implant tissues in a good condition.
