About this study

Short-term comparison of clinical application effects of Astra OsseoSpeed EV short implants and conventional implants for maxillary sinus elevation

Read the detailed description
  1. If the survival rate, marginal bone resorption , complications and patient satisfaction of the short implant group are comparable or better than those of the conventional implant group, then short implants can be regarded as an effective treatment option for insufficient alveolar bone in the posterior teeth area. Thus, in clinical practice, the investigators can utilize short implants combined with transcrestal sinus floor elevation, or even implant short implants to help patients with certain insufficient maxillary bone complete implant restoration without resorting to more complex, costly and more invasive external elevation surgery to increase the length of posterior teeth implants in the maxillary region.
  2. If it is found that the short implant group has a higher incidence of complications or a lower long-term survival rate, further exploration of its indications and optimization of surgical strategies is required.

Questions about this trial

What is this clinical trial studying?

A study testing short implants (L=6.3mm), short implants (L=8mm) and conventional implants (L=9mm) in people with Missing Teeth, run by Linhu Wang at 1 site in China.

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 3 inclusion and 8 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: opening soon, as of the sponsor's last update on 16 Dec 2025. 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 China. 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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact lin hu Wang, Doctoral (+8618086060633, 316036445@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Various complications (time frame: From having a tooth implant to one year after wearing the dentures). 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 16 Dec 2025.
