Brief summary in lay language

The aim of the study is to investigate the implant-guided implantation of one-piece full-ceramic implants with a new, sleeveless drilling template. Due to the guided implant bed preparation and insertion of the implants an optimal implant position is to be achieved with regard to the planned prosthetic supply and the optimal use of the existing bone offer. The drill template to be examined here does not use metal sleeves to guide the drills, but guides the head of the surgical elbow via external attachments. The bores can thus be made contactless, without contact with a titanium guide sleeve.

Brief summary in scientific language

In this pilot study, the accuracy of the implant placement is to be determined in relation to the previously virtually planned position. In addition, the feasibility and the indicative limits for the drilling template used here should be described. The null hypothesis is that there is no difference in accuracy to conventional drilling templates with guide sleeves. It is a monocentric prospective controlled clinical trial. 12 patients who require the implant-prosthetic restoration of a gap or / and a free-end situation in the upper or lower jaw participate in the study. Primary target size is the degree of correspondence between clinical implant position and planning. As a secondary target, technical complications are investigated during implant bed preparation.

Interventions, Observational Groups

Arm 1:
Template-guided implantation of one-piece full-ceramic implants with a new, sleeveless drilling template.

Endpoints

Primary outcome:
Deviation of the planned implant position from the actual position. The deviation is described by the distance at the crestal implant penetration point, at the apical end of the implant, at the height of the implant and in the axis deviation. The measurement will be performed immediately after insertion of the implant.
Secondary outcome:
Indication limitations for the stencil design of 2ingis. Clinical complications: Insufficient template content, eg. Technical complication: stencil fracture or the like. Feasibility study for a subsequent multicentric field study. The feasibility study should give evidence of a sufficient clinical accuracy of the used templates and work out possible indication restrictions. All recordings are made on the day of Implantation. No further follow-up is performed.

18 Years
Maximum Age:
no maximum age
Additional Inclusion Criteria:
Gaps in the upper and / or lower jaw tooth area Free-ending situations in the upper and / or lower jaw area The extraction is at least 3 months.
