Esthetic, Clinical and Radiographic Outcomes of Immediately Placed Implants (Type 1) and Early Placed Implants (Type 2)

Jaw, Edentulous, Partially Clinical Trial

Official title:
Esthetic, Clinical and Radiographic Outcomes of Immediately Placed Implants (Type 1) and Early Placed Implants (Type 2)

Clinical Trial Summary

The investigators are asking subjects to take part in a research study of soft tissue (gums) and bone (jawbone) healing around dental implants following tooth extraction. The investigators want to compare how the gums and the bone changes shape with healing in two different scenarios:

1. When the implant is placed at the same time the tooth is extracted.

2. When the tooth is extracted and then left to heal for a period of 4 to 8 weeks before the implant is placed.

Previous studies have shown that both methods work and can give good results. In fact the two methods are used routinely as part of standard care but it is not known if the two procedures are equally good since they have never been compared in one same research study.

Clinical Trial Description

This controlled, randomized clinical trial (RCT) is designed to compare soft and hard tissue dimensional changes for two commonly used approaches for replacing a recently extracted tooth by means of a dental implant, i.e. immediate implant placement (Type 1) or early implant placement (Type 2). Additionally, this study will evaluate the association between the osseous anatomy and implant position with soft and hard tissue changes.

Extraction sites will include maxillary and mandibular anterior and premolar teeth having intact adjacent teeth. Implants placed for this study will be SLA surface, bone level design, Straumann BL RC (Bone Level Regular Cross-fit ) 4.1mm or BL NC (Bone Level Narrow Cross-fit ) 3.3mm diameter implants at 8, 10, 12 or 14mm in length.

Immediate implant placement (Type 1) resulting in a horizontal defect dimension (HDD) will receive bone grafting, using freeze dried bone allograft (FDBA)(Straumann Allograft GC®) and will be covered by a resorbable membrane (BioGide®).

For the implants randomized to type 2 implant placement, the extraction socket will be filled with a collagen plug and allowed to heal for 4 to 8 weeks before the implant will be placed. Simultaneous guided bone regeneration (GBR) will be performed using FDBA (Straumann Allograft GC®)and a resorbable collagen membrane (BioGide®). The type 2 implant placement procedure will follow the guidelines as described by Buser et al. (2008).

All implant placement will follow standard protocols utilizing tapping and placement according to the manufacturer's guidelines. ;
