English abstract
The aim of this study was to compare porcelain-veneered implant-supported FDPs based on zirconium dioxide and titanium respectively. Sixteen patients received 18 implant-supported partial fixed dental prostheses (FDPs); 8 titanium-based and 10 zirconia-based. The FDPs were randomized between the two material groups. Follow-up of the patients was performed at 3 months and thereafter once a year. An assessment protocol based on the California Dental Association (CDA) quality assessment system was used. Results: All patients were seen at follow-up. The mean time of clinical service at follow-up was 15,2 months (range 12-24 months). All restorations were in place and all patients were satisfied with the treatment. No technical complications were noted in either group. Minor biological complications, in the form of plaque and/or mucositis, not affecting the survival of the restorations were noted for six of the titanium-based restorations and two of the zirconia-based restorations. The difference between the two material groups was not statistically significant. The outcomes of both materials were comparable. Short term data from this study suggests that porcelain-veneered implant-supported partial FDPs based on zirconia and titanium are satisfactory and equal treatment options. This conclusion is however preliminary as it is based on a small number of patients and short-term follow-up. Long-term follow-up of larger groups of patients is needed before more definite conclusions can be made.
Swedish abstract
Målsättningen med studien var att jämföra implantat-stödda partiella broar av titan-porslin respektive yttria-stabiliserad zirkoniumdioxid med ytporslin. Sexton patienter fick sammanlagt 18 broar; 8 av titan-porslin och 10 av yttria-stabiliserad zirkoniumdioxid-porslin. Broarna fördelades randomiserat till respektive material-grupp. Patienterna följdes upp och kontrollerades en första gång efter 3 månader och därefter en gång per år. Ett bedömningsprotokoll baserat på California Dental Association (CDA) kriterier användes. Alla patienter genomförde kontrollbesöken. Genomsnittlig uppföljningstid var 15,2 månader (12-24 månader). Alla konstruktioner var i funktion vid uppföljning och alla patienter var nöjda med behandlingen. Inga tekniska komplikationer noterades i någon av grupperna. Biologiska komplikationer av ringa betydelse, plack och/eller mucosit, som inte påverkade konstruktionernas överlevnad noterades vid 6 av titan-keramik broarna och 2 av zirkonia-porslins broarna. Skillnaden var inte statistiskt signifikant. Sammanfattningsvis kan vi i denna studie konstatera att båda materialen fungerade jämförbart. Data från denna studie antyder att implantat-stödda partiella broar av titan-porslin respektive zirkoniumdioxid med ytporslin uppvisar goda resultat över kort sikt. Studier med fler patienter och längre uppföljningstid rekommenderas emellertid innan definitiva slutsatser kan dras.
