About this study

Official title: Associations of Alveolar Bone Loss, Clinical Parameters and Interleukin-1β Levels in One and Two Stage Surgical Procedures: A Randomized Prospective Trial

The present study was compared the level of alveolar bone loss, clinical parameters and IL-1β in PICF in one- or two-stage surgical procedures. Half of the patients were performed tissue level implant while other half were performed bone level implant.

Read the detailed description

The present study included 40 healthy patients (24 males and 16 females; mean age, 30.75 ± 8.58 years) who had one tooth absent in the mandible, at the Department of Periodontology, Dicle University, Diyarbakir, Turkey, between 2010 and 2011. All patients were informed in detail about the study protocol, and they were asked to sign informed consent forms. Ethics committee approval was obtained from Dicle University Ethics Committee for this study (D.Ü.D.F.E.K.2010/02)

This study was designed as a prospective, randomized, controlled study. Randomization was performed prior to surgery by opening a sequentially numbered sealed envelope corresponding to the patient recruitment number. Investigators received randomization instructions only after enrolling a subject and immediately prior to surgery. The participants were randomly divided into two groups. A one-stage surgical procedure was performed on 20 patients (Group I) and a two-stage surgical procedure was performed on the other 20 patients (Group II). The primary outcome of the study was a change in alveolar bone level at the implant site between T0 and T2 months after surgery measured on CBCT. The secondary outcomes between T0, T1, and T2 were changes the level of IL-1β PICF, probing pocket depth (PPD), modified plaque index (mPI), modified gingival index (mGI), and modified bleeding index (mBI). All implants (Straumann AG, Waldenburg, Switzerland) were inserted by the same periodontist (T.T.Y.) in the present study. Pre-surgical radiographic evaluation was conducted using CBCT. Before surgery, the patient's mouth was rinsed with chlorhexidine mouthwash. After local anesthesia, full thickness flaps were reflected, and osteotomies were prepared in the first mandibular molar sites. In these surgical operations, 20 tissue-level and 20 bone-level dental implants 12 mm in length and 4.8 mm in diameter were inserted in Group I and Group II, respectively. Three months later, second-stage surgery was performed and implant exposed into the oral cavity. Cover screw was removed and replaced with healing abutments. Three months waited for second surgery in bone level implants. Patients of both groups were enrolled in a monthly periodontal/peri-implant maintenance program after abutments were connected in which, full mouth scaling was performed around all natural teeth and implant surfaces. Oral hygiene instructions regarding regular tooth brushing were given and patients were encouraged to floss the teeth and periimplant surfaces daily. There was no implant failed during the study and adverse event of these treatments.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. change of alveolar bone level

    The primary outcome of the study was a change in alveolar bone level (height in mm) at the 40 implant site between T0 and T2 months after surgery measured on CBCT. All measurements were performed at four sites (mesial, distal, buccal, and lingual) around each dental implant at T0 and T2. These four values were then averaged for each dental implant.

    • Alveolar bone level were measured in millimeters (height in mm) from a fixed reference point on the implant (implant shoulder to the most coronal position of the crestal bone contacting the implant).

    Measured: 0 and 6 month

Secondary outcomes (5)
  1. changes level of IL-1β

    The secondary outcome of the study was change the level of IL-1β pg/ml between T0, T1, and T2. To obtain PICF, filter paper strips were gently inserted into the peri-implant crevice for 30 s at the mesial, distal, buccal, and lingual sites of the dental implant. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used.

    • The level of IL-1β pg/ml (weight in picogram, weight in milliliter)

    Measured: 0, 3, and 6 month

  2. changes of PPD

    The secondary outcome of the study was change of the PPD between T0, T1, and T2. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used.

    • Probing pocket depth (PPD) (depth in mm), were measured

    Measured: 0, 3, and 6 month

  3. changes of Modified plaque index

    The secondary outcome of the study was change of the Modified plaque index between T0, T1, and T2. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used.

    • Modified plaque index (0=no plaque, 1= mild plaque, 2= moderate plaque, 3=severe plaque).

    Measured: 0, 3, and 6 month

  4. changes of Modified gingival index

    The secondary outcome of the study was change of the Modified gingival index between T0, T1, and T2. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used.

    • Modified gingival index (0=healthy, 1=mild inflammation 2= moderate inflammation 3=severe inflammation).

    Measured: 0, 3, and 6 month

  5. changes of Modified bleeding index

    The secondary outcome of the study was change of the Modified bleeding index between T0, T1, and T2. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used.
