• 1 other identifier: 0991-10
• Study Type: interventional
• Target: 24
• Locations: 1 country

Brief Summary

The aim of this randomized clinical trial is to evaluate the volumetric analysis of peri-implant soft tissues after 3 months of the use of a prefabricated healing abutment with scan peg in comparison to customized healing abutment.

Conditions

Dental Implants; Dental Implants, Single-tooth

Keywords

Dental implants; single missing posterior teeth; peri-implant soft tissues

Outcome Measures

Primary Outcomes (1)

• Measurement of peri-implant soft tissues volume

  Each participant will undergo volumetric analysis of peri-implant soft tissues after 3 months healing either after using prefabricated healing abutment with scan peg in comparison to customized healing abutment using a 3D meteorology software (GOM inspect). It will be measured in millimeter cube

  3 months

Study Arms (2)

Prefabricated healing abutment with scan peg (Neoss implant system, Harrogate, England)

EXPERIMENTAL

12 participants will receive single posterior implants by fully guided implant protocol followed by placement of prefabricated healing abutment with scan peg having convex emergence profile

Other: Prefabricated healing abutment with scan peg

Customized healing abutment

ACTIVE COMPARATOR

12 participants will receive single posterior implants by fully guided implant protocol followed by placement of custom healing abutment having concave emergence profile

Other: Customized healing abutment
