Fünf der Implantate mit den Kronen gingen aufgrund biologischer Misserfolge verloren. Zwei Kronen (2.9%) mussten aufgrund technischer Misserfolge neu angefertigt werden. Die totale Misserfolgsrate betrug sieben (10%). I‐I FPD: Bei 29 Patienten, welche mit 33 implantatgetragenen Rekonstruktionen versorgt worden waren, betrug die totale Anzahl an fehlgeschlagenen I‐I FPD 2 (6.1%). I‐T FPD: Bei 21 Patienten wurden gemischte Implantat‐Zahn getragene Rekonstruktionen eingegliedert. Die Anzahl der FPD mit Misserfolgen betrug 7 (31.8%). Mit I‐I FPD traten im Vergleich zu I‐T FPD statistisch signifikant weniger biologische Misserfolge auf (ANOVA, Bonferroni, <i>P</i>=0.022). Die I‐T FPDs zeigten im Vergleich zu den zwei anderen Gruppen von Rekonstruktionen signifikant mehr technische Misserfolge (<i>P</i>=0.003; <i>P</i>=0.031). Konsequenzen der Komplikationen: Das Auftreten eines Retentionsverlustes als Komplikation erhöhte die Odds ratio, in einem technischen Misserfolg zu enden, auf 17.6 (<i>P</i><0.001). Aehnlich erhöhte das Auftreten einer Porzellanfraktur die Odds ratio, dass die Rekonstruktion nach 10 Jahren in einem Misserfolg endet, auf 11 (<i>P</i>≤0.004). Die Behandlung einer Periimplantitis erhöhte im Vergleich zu Implantaten ohne solche Therapie die Odds ratio, dass ein biologischer Misserfolg auftritt, auf 5.44 (<i>P</i>≤0.011).</p><p><b>Schlussfolgerung: </b> Die drei Gruppen von Rekonstruktionen zeigten deutliche Unterschiede in der Art der Komplikationen und Misserfolge.

Five of the implants with the crowns were lost because of biological failures. Two crowns (2.9%) were remade because of technical failures. Total failure amounted to seven (10%). Implant borne fixed partial dentures (I‐I FPD): In 29 patients who had been restored with 33 implant borne suprastructures, the total number of failed I‐I FPD was 2 (6.1%). Tooth–implant borne fixed partial dentures (I‐T FPD): In 21 patients, 22 mixed tooth–implant borne reconstructions were constructed. The number of failed FPD reached 7 (31.8%). Statistically significantly fewer biological failures occurred with I‐I FPD compared with the I‐T FPDs (ANOVA, Bonferroni, P=0.022). The I‐T FPDs experienced statistically significantly more frequent technical failures compared with the other two groups of suprastructures (P=0.003, 0.031). Consequences of complications: The occurrence of loss of retention as a complication increased the odds ratio (OR) to 17.6 (P<0.001) to end up in a technical failure. Similarly, the event of a porcelain fracture increased the OR for the suprastructure to be a failure at 10 years to 11.0 (P≤0.004). Treatment of periimplantitis increased the OR to 5.44 (P≤0.011) to result in a biological failure compared with implants in which this type of treatment was not applied.</abstract><abstract>Conclusion: The three groups of suprastructures demonstrated marked differences in their patterns of failures and complications.

Quatre vingt‐neuf patients ont été suivis : 34 hommes (38%) et 55 femmes (62%). A l'examen après dix années (de huit à douze ans) ils avaient 59 ans (de 28 à 88 ans). SC : 48 patients avaient eu 69 couronnes uniques sur 69 implants. Cinq des implants avec couronnes avaient été perdus suite à des problèmes biologiques. Deux couronnes (3%) ont été refaites suite à des problèmes techniques. L'échec total s'élevait à sept (10%). I‐I FPD : chez 29 patients qui avaient subi une restauration à l'aide de 33 superstructures sur implants, le nombre total d'échecs I‐I FPD était de 2 (6%). I‐FPD : chez 21 patients, 22 reconstructions mixtes dents/implants ont été construites. Le nombre d'échecs FPD s'élevait à sept (32%). Significativement moins d'échecs biologiques arrivaient avec I‐I FPD comparés aux I‐T FPD (ANOVA, Bonferroni, P=0,022). Les I‐T FPD avaient significativement plus souvent des échecs techniques comparés aux deux autres groupes de superstructures (P=0,003, P=0,0031). Conséquences des complications : l'apparition de perte de rétention en tant que complication augmentait les facteurs de risque à 17,6 (P<0,001) pour se terminer en échec technique. De même une fracture de porcelaine augmentait le facteur de risque de la superstructure à dix années à 11 (P<0,004). Le traitement de la paroïmplantite augemntait le facteur de risque à 5,44 (P≤0,011) pour résulter en un échec biologique comparé aux implants dans lesquels ces types de traitement n'étaient pas appliqués Ces trois groupes de superstructures ont montré de grandes differences entre leurs voies d'échecs et de complications. Les complications augmentent le risque d'échec.</abstract><abstract>Ziel: Prospektiv über einen Zeitraum von 10 Jahren die Häufigkeit von technischen und/oder biologischen Komplikationen und Misserfolgen, welche in einer Kohorte von aufeinander folgenden teilbezahnten Patienten mit festsitzenden Rekonstruktionen auf Implantaten des ITI® Dental Implant Systems auftreten, auszuwerten.</abstract><abstract>Methoden: 89 Patienten standen zur Verfügung, 34 (38.2%) waren männlich, 55 (61.8%) waren weiblich.
