8 januari 2021 bijgewerkt door: Wen Luo

Clinical and Radiographic Evaluation of a Cross-shaped Incision Technique to Thick-gingiva and Thin-gingiva Patients Treated With Implant-supported Fixed Prosthesis

To evaluate a cross-shaped incision technique to thick-gingiva and thin-gingiva patients treated with implant-supported fixed prosthesis.

Studie Overzicht

Gedetailleerde beschrijving

Objective: To evaluate a cross-shaped incision technique to thick-gingiva and thin-gingiva patients treated with implant-supported fixed prosthesis. Methods and Materials: 55 patients received cross-shaped incision were assigned into thick-gingiva group (29 cases) and thin-gingiva group (26 cases). Follow-up examination was carried out 3 and 12 months after final restoration. Clinical and radiographic evaluation including gingival papilla height, modified plaque index, modified sulcus bleeding index, periodontal depth, and crestal marginal bone level were utilized.

Studie Bevolking

The study samples were comprised of patients who had been treated with one bone-level implant (Osstem, Korea) insertion in the first molar region. Fifty-five subjects were selected from the patients who came to the Department of Oral Implantology, West China Hospital of Stomatology, Sichuan University in China between June 2018 and June 2020.

Beschrijving

Inclusion Criteria:

  1. Good general health, no chronic systemic diseases.
  2. All subjects included in this study needed to have one missing premolar or molar teeth with adjacent natural teeth.
  3. All subjects included in the study had been treated with one bone-level implant insertion in the premolar or molar region.

Exclusion Criteria:

  1. Active periodontal infections.
  2. Heavy smoking habit (>10 cigarettes per day).

Cohorten en interventies

Groep / Cohort
Interventie / Behandeling
thick-gingiva group
After insertion of the probe into the facial aspect of the sulcus, the peri-implant biotype can be categorized as thick-gingiva (outline if the probe cannot be seen through the gingival)
thin-gingiva group
After insertion of the probe into the facial aspect of the sulcus, the peri-implant biotype can be categorized as thin-gingiva (outline of the probe can be seen through the gingival)
The biotype of gingival was also determined by periodontal probe.

Wat meet het onderzoek?

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
papilla height
Tijdsspanne: Between June 2018 and June 2020.
Presence/absence of papilla height was assessed visually
Between June 2018 and June 2020.
Modified Plaque Index (mPI)
Tijdsspanne: Between June 2018 and June 2020.
plaque accumulation around the marginal peri-implant tissue was assessed
Between June 2018 and June 2020.
Modified Sulcus Bleeding Index
Tijdsspanne: Between June 2018 and June 2020.
the bleeding tendency of the marginal peri-implant tissue was evaluated
Between June 2018 and June 2020.
Probing Depth (PD, in millimeters)
Tijdsspanne: Between June 2018 and June 2020.
PD was assessed at the mid-buccal, mid-oral, mesial and distal aspects of each implant with a standard periodontal probe, and final value was determined by the average of four aspects
Between June 2018 and June 2020.
Gingival margin level
Tijdsspanne: Between June 2018 and June 2020.
Gingival margin level was assessed by calculating the vertical distance between the most apical point of gingival margin at the buccal aspect of the crown and line connecting the peak of the adjacent mesial and distal natural teeth
Between June 2018 and June 2020.

Secundaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
first bone-implant contact (fBIC) and implant shoulder (IS)
Tijdsspanne: Between June 2018 and June 2020.
the landmarks of first bone-implant contact (fBIC) and implant shoulder (IS) were used for measurements. fBIC-IS was defined as the vertical distance the first bone-implant contact to implant shoulder, and the distance was assessed at the mesial and distal aspect of implant, respectively. When the marginal crestal bone was located coronal to the IS, a positive (+) value was given, where a negative (-) value when located apically to the IS, the value was deemed as zero when IS and fBIC coincided.
Between June 2018 and June 2020.
