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.
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.

| Split-Mouth Placement of an implant with a moderately rough surface (DCC). | Device | Surgical placement of a dental implant in canine area (left or right, assigned by flipping a coin) of the mandibular bone of the patient. |
| Measure | Description | Time Frame |
|---|---|---|
| The effect of surface roughness on long-term crestal bone remodelling. | 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. | From enrollment until 8 years. |
| Measure | Description | Time Frame |
|---|---|---|
| Oral Health Quality of Life (OHQoL) | 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. | Assessed after 1 and 8 function years. |
| Peri-implant Health: Probing pocket depth |

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).
