Interventions

Group 1: Totally 60 patients in which the replacement of a missing tooth (single-tooth gap) in the posterior region in the upper or lower jaw is planned by an implant-supported supply, participate in

Eligibility

Sex/Gender

All

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: Single tooth gap in the maxillary posterior region Single tooth gap in the lower jaw posterior region he extraction is back at least 3 months. It made exclusively early implantation (3 - 6 Months post-extraction) and late implantations (> 6 months post-extraction). The space boundaries may be natural teeth or implants. There must be a contralateral natural tooth may be present as a reference tooth, as well as an antagonistic dentition. The patient has good oral hygiene and compliance. Informed consent is present.

Exclusion criteria

Exclusion criteria: Persons under 18 or legally incompetent persons Untreated acute periodontitis Heavy smokers (more than 10 Zig / d.) Use of bisphosphonates Pregnant Alcohol or drug addicts Patients with an infectious disease such as hepatitis or HIV or AIDS Patients with severe diabetes m. Immediate implantation

Design outcomes

Primary

Measure	Time frame
Primary target of the Analysis is the loss of the implant differentiated in an Observation period of 5 years after Insertion by the two Groups of different material selection for the prosthetic supply.	—

Secondary

Measure	Time frame
Biological and technical complications at the implant-crown complex Clinical parameters: probing depth (PD), Ginigival Index (GI), plaque index (PI), bleeding on probing (BOP), implant stability (Periotest) and bone resorption (standardized radiographs). echnical complications: Chipping, screw loosening or Screws fractures. Microbiological effects of different crown materials. Accuracy of implant position after 3-D planning and implementation without a template. abrasion of different crown materials at the crown and the antagonistic teeth. Aesthetic result (Pink Aesthetic score after Fürhauser et al.2005 Patient satisfaction (VAS) Efficiency of procedures. This aspect of the study uses the data of the randomized clinical trial of a semi-mounted cost-benefit analysis in the test and control group with the described method (Piggy-Back). The economy is faced based on the documented cost of treatment (dental, dental services and material costs) of patient satisfaction. The parameters are collected at the following time points: baseline (1 week after onset of the crown), 6 Monte, 1, 2, 3, 4 and 5 years. Deviating from this the microbiological survey findings is done after 6 months and 2 years	—
