Outcome measures
Primary outcome
Primary outcome measure is the health of peri-implant mucosal and hard tissues
as expressed through:
- Bleeding On Probing (BOP)
- Probing Pocket Depth (PPD)
- Recession (REC) compared incisal edge picture with pocket probe measurement
Secondary outcome
Secondary outcome measures include:
- Plaque, calculus and gingival index (PCGI) according to Mombelli
- Marginal Boneloss (BL) as measured on standard intra-oral X-ray pictures
(solo recording, Rinn holder with putty)
- Pink and White aesthetic score (PES/WES) of Belser and Buser, index Groningen
ICAI according to Meijer, Papilla-Index (PI) according to JEMT
- Patient Satisfaction (SAT) according to standard questionnaire
- Microbiological (MB) parameters
- Spectro-photometry (SP) of both the crown and the soft tissue
Background summary
Titanium (Ti) has been the *gold standard* ground material for the fabrication
of oral endosseous implants for over four decades. The clinical-functional
results are favourable, with well-documented implant survival rates in
partially edentulous patients exceeding 95% after 5 years of functional loading
of implants supporting either single crowns or fixed partial dentures
(Pjetursson et al. 2007). Nevertheless, titanium also has its drawbacks.
High-strength ceramics, in particular zirconia (ZrO2) may be an attractive
alternative. After sintering, Y-TZP has mechanical properties comparable to
those of stainless steel. Both bone and soft tissues respond favourable to
Y-TZP (Manicone et al. 2007). In vivo studies comparing Ti and Y-TZP implants
and abutments have predominantly been concerned with the bone-implant response
and to a lesser degree with the soft tissue response (Wenz et al. 2008).
Comparable percentages of bone-implant contact between Ti and Y-TZP implants
have been observed in animal studies (Wenz et al. 2008; Andreiotelli et al.
2009).
Study objective
We aim to conclude on the application of Zirconia dental implants in the
aesthetic zone where we feel that it would have the most advantages as compared
to titanium implants. Such an implant system is basically comprised of 2
components: a zirconia implant that osseointegrates with the alveolar bone (a)
and a fiberglass post and core that is cemented to the implant and acts as an
abutment for a ceramic crown. Clinical, (micro-) biological, and radiographical
data are collected and compared to the contralateral natural tooth.
Study design
This pilot study is designed as a prospective case series study. A group of 30
patients in need of a single implant crown replacing a front tooth in the
aesthetic zone of the maxilla (teeth 15-25) are selected.
Intervention
All patients will recieve an implant in order to replace a missing tooth.
Study burden and risks
About 3 hours extra time, no extra charge or arrangements.
