Conditions

Oral Health Quality of Life (OHQoL) Was Assessed, the Effect of Surface Roughness on Crestal Bone Remodelling, The Effect of Surface Roughness on Peri-implant Health

Keywords

implant surface, implant-supported overdenture, oral health quality of life, implant survival, hybrid implants, moderately rough implants

Brief summary

This study looks at how the surface texture of dental implants affects the surrounding bone and the overall gum health over time. It compares two types of implant surfaces: one partially smooth and one slightly rough. The researchers also check how these implant treatments impact patients' quality of life related to oral health after 1 year and again after 8 years.

Detailed description

This split-mouth randomized controlled trial aimed to assess the effect of surface roughness on long-term crestal bone remodelling and peri-implant health, comparing hybrid and moderately rough implants. As a secondary aim, Oral Health Quality of Life (OHQoL) was assessed after 1 and 8 function years.

Interventions

DEVICESplit-Mouth Placement of an implant with a moderately rough surface (DCC).

Surgical placement of a dental implant in canine area (left or right, assigned by flipping a coin) of the mandibular bone of the patient.

DEVICESplit-Mouth Placement of an implant with a hybrid surface (MSC).

Surgical placement of a dental implant in canine area (left or right, assigned by flipping a coin) of the mandibular bone of the patient.

Intervention model description

In this split-mouth randomized controlled trial patients received a mandibular overdenture supported by 2 different implants. One implant had a moderately rough surface (DCC) and one implant had a hybrid surface (MSC).

Design outcomes

Primary

MeasureTime frameDescription
The effect of surface roughness on long-term crestal bone remodelling.From enrollment until 8 years.The effect of surface roughness on long-term crestal bone remodelling is evaluated by recording crestal bone loss (mm) on intra-oral periapical radiographs of the implants.

Secondary

MeasureTime frameDescription
Oral Health Quality of Life (OHQoL)Assessed after 1 and 8 function years.The patients were asked to complete an Oral Health Impact Profile-14 (OHIP-14) questionnaire. Score varies beween min.0 and max.56. Lower values indicate better conditions.
Peri-implant Health: Probing pocket depthAt one year, 6 years, 8 years and 10 years of follow-upProbing pocket depth (mm) at 4 sites around the implant
Peri-implant health: Bleeding on probingAt one year, 6 years, 8 years and 10 years of follow-up.Bleeding on probing (yes/no) at 4 sites around the implant
Peri-implant Health: Plaqueat one year, 6 years, 8 years and 10 years of follow-up.Plaque (yes/no) at 4 sites around the implant
