Study summary

This study investigates the use of a new healing cap which, through altered design and choice of material, has been improved when it comes to minimizing the risk of it falling off as well as increasing patient comfort.

Read the detailed description

This study will primarily investigate the use of a new healing cap, Healing cap II. The new healing cap has the same function as previous healing caps, but it soft instead of hard. Due to this, the healing cap is anticipated to not fall off as easily, but at the same time does not risk transferring larger forces than previously to the implant. Secondly, the patients will start using the sound processor 1-2 weeks after surgery. The implant stability will be monitored before and after loading by the use of resonance frequency analysis, an established method to evaluate and monitor osseointegrated implants.

What researchers measure

Primary outcomes

  1. Skin reactions according to Holgers

    Focus is on healing, post-operative complications and skin reactions after the first 7-14 days after surgery.

    Time frame: At time of sugical follow up visit (visit window of 7-14 days after surgery)

Secondary outcomes

  1. Fitting of sound processor at surgical follow-up visit

    Implant stability is monitored before and after sound processor fitting through ISQ and clinical assessments.

    Time frame: At time of surgical follow up visit (visit window of 7-14 days after surgery)

Other outcomes

  1. Surgical time

    Time taken to perform the surgery

    Time frame: Recorded at surgery visit

  2. Surgical complications

    Any complications during and after surgery

    Time frame: At the surgical visit

  3. Surgical complications

    Any complications during and after surgery

    Time frame: At time of surgical follow up visit (visit window of 7-14 days after surgery)

  4. Implant stability

    Time frame: Duration of study (12 months of enrollment)

  5. Use of Healing cap II

    Ease of use of Healing cap II and effect on surgical dressing

    Time frame: At the surgical visit

  6. Use of Healing cap II

    Ease of use of Healing cap II and effect on surgical dressing

    Time frame: At time of surgical follow up visit (visit window of 7-14 days after surgery)

  7. Skin healing at first follow-up visit

    Time frame: At time of surgical follow up visit (visit window of 7-14 days after surgery)

  8. Pain and numbness

    Time frame: Duration of study (12 months of enrollment)

  9. Time of fitting and type of sound processor
