Comparing narrow and standard dental implants with bone regeneration

Narrow Diameter Implants Versus Standard Diameter Implants With Simultaneous Bone Regeneration For The Treatment Of Atrophic Posterior Area

This study is testing whether narrow dental implants work better than standard ones for patients who need bone regeneration and are looking for long-term success and satisfaction.

What this trial studies

This clinical trial aims to compare the effectiveness of narrow dental implants (NDI) versus standard dental implants (SDI) in patients requiring bone regeneration. The study will evaluate long-term survival rates, complications, and patient satisfaction associated with both types of implants. Participants will undergo a randomized split-mouth design, allowing for direct comparison within the same patient. The trial will focus on patients with specific bone dimensions and healthy periodontal status to ensure optimal conditions for implant placement.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with healthy periodontal status and specific bone dimensions suitable for implant placement.

Not a fit: Patients with active periodontal disease, systemic conditions contraindicating surgery, or those who smoke heavily may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the best implant options for patients with limited bone width, potentially improving dental restoration outcomes.

How similar studies have performed: Previous studies have shown high survival rates for narrow implants, indicating that this approach has been successful in similar contexts.

Eligibility criteria

Inclusion Criteria:

Patients:

* 18 years old
* Healthy periodontal status (absence of generalized probing pocket depth (PPD) \<4mm)
* Oral hygiene levels (FMPS \<20 and FMBS \<20)

Site:

* Ridge width of \>5mm and \<6.5mm and minimum bone height of 10mm prior evaluation on a CBCT scan
* Presence of antagonistic natural tooth or fixed prosthetic restoration
* Presence of adjacent teeth
* One maxillary or mandibular premolars
* Minimum of 3mm of keratinized tissue over the bone crest (20)
* Bone regeneration within the limits of the prosthetic restoration.

Implants:

* Unitary prosthesis
* Screwed retained restorations

Exclusion Criteria:

Patients

* Presence of active chronic or aggressive periodontal disease
* Presence of systemic disease which contraindicate surgery (patients with an ASA ≥ 3)
* Drugs or medications which may alter the results (chronic intake of analgesic medication)
* Smokers (\>10cig/day)
* Pregnant women
* History of head and neck radiotherapy.

Site

* Anterior area (from 1.3 to 2.3 and from 3.3 to 4.3) and molar area
* Previous guided bone regeneration
* Location where there is not sufficient restorative space (mesio-distally \<8mm for every restoration unit and \<5mm from the bone crest to the antagonist)
* Implant dehiscence of more than 2/3 of the implant.

Implant

* Implants which cannot be restored with a screwed restoration
* Implants which doesn't reach a manual implant stability
* implants which after placement doesn't reach a favourable position according to the restoration.
