About this study

Official title: Horizontal and Vertical Dimensional Changes of Peri-implant Facial Bone Following Placement of T3 Implants: a 1-year Cone Beam Computed Tomography Study

40 consecutive adult patients, requiring the insertion of dental implants in the aesthetic area (from second premolar to second premolar) will be enrolled in the study. At the time of surgery, a full thickness flap will be elevated, the implant bed will be prepared according to the manufacturer's instruction and the implants will be then seated into the bone. T0 corresponds to the time of implant insertion, T1 to the time of healing abutment's connection (T0=T1 for single stage implants), and T2 corresponds to 1-year follow-up from healing abutment's connection.

Cone Beam Computed Tomography (CBCT) scans will be taken immediately after abutment connection (T1) and 1-year after (T2). The midsagittal cut of each implant will be identified, and measurements will be made at predetermined levels. Horizontal facial bone thickness (HFBT) and Vertical facial bone level (VFBL) will be measured. HFBT will be measured at 0, 3, 6 and 9 mm apical to the implant platform. VFBL wil be the perpendicular distance from the implant platform to the most coronal point of the facial bone. Changes between T1 and T2 will be calculated.

Read the detailed description

The long term results and benefit of implant insertion in the aesthetic area have been well documented.

In the past few years, facial dimensional changes to the alveolar process following implant placement are object os study for both humans and animals investigations Recent studies suggest that platform switching decreases bone loss by 30% to 50%. It seems that the creation of a biologic width affects peri-implant bone loss to a significant extent and that platform switching is effective when the mucosal thickness allows the establishment of an horizontal biologic width.

A new implant with an hybrid surface (T3) has been recently launched by Biomet 3i.Aim of the present study will be to evaluate the degree of 3D marginal bone remodelling around T3 Prevail implants.

MATERIALS \& METHODS:

40 consecutive adult patients, requiring the insertion of dental implants in the aesthetic area (from second premolar to second premolar) will be enrolled in the study. At the time of surgery, a full thickness flap will be elevated, the implant bed will be prepared according to the manufacturer's instruction and the implants will be then seated into the bone. Implants can be placed both with a single-stage or two-stage procedure. Implants inserted with a two-stage procedure will be re-opened after a submerged period of three months.

T0 corresponds to the time of implant insertion, T1 to the time of healing abutment's connection (T0=T1 for single stage implants), and T2 corresponds to 1-year follow-up from healing abutment's connection.

It is supposed that the creation of the biological width starts with the healing abutment's connection.

CBCT scans will be taken immediately after abutment connection (T1) and 1-year after (T2). The midsagittal cut of each implant will be identified, and measurements will be made at predetermined levels. Horizontal facial bone thickness (HFBT) and Vertical facial bone level (VFBL) will be measured. HFBT will be measured at 0, 3, 6 and 9 mm apical to the implant platform. VFBL wil be the perpendicular distance from the implant platform to the most coronal point of the facial bone. Changes between T1 and T2 will be calculated.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • implant insertion and abutment connectionProcedure or surgery

    After implant insertion, immediate or in healed ridge, the titanium abutment with switching platform will be connected

What is being measured

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

  1. horizontal buccal bone thickness

    On Cone Beam images, the horizontal dimensional changes of peri-implant facial bone will be measured

    Measured: 12 months after abutment connection

Secondary outcomes (1)
  1. vertical bone level

    On Cone Beam images, the vertical dimensional changes of peri-implant facial bone will be measured

    Measured: 1 year after abutment connection

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing implant insertion and abutment connection and osseointegrated implant in people with Jaw, Edentulous, Partially, run by Proed, Torino, Italy at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

horizontal buccal bone thickness (time frame: 12 months after abutment connection). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2016; AzTrials last refreshed its copy on 6 Nov 2026.
