Yes. The Patent™ implant system is backed by two long-term clinical studies — Brüll 2014 and Becker 2017.
The retrospective study (Brüll 2014) examined the clinical performance of Patent™implants on 74 consecutively treated patients with 121 implants over 3 years. The following are the key takeaways from the study:
• 96.5% implant survival rate, comparable with titanium.
• Implants were placed immediately in extraction sockets and in healed sites.
• Stable or increased marginal bone levels.
• Bleeding on probing (BOP) less around implants than other teeth.
• Probing pocket depth (PPD) less around implants than other teeth.
• Soft tissue conditions were better than around titanium implants.
• Only one reported implant fracture.
• No fractures of the glass fiber posts.
The prospective study (Becker 2017) examined the clinical performance of Patent™ implants on 52 patients with single tooth gaps in the posterior maxilla over 2 years. The following are the key takeaways from the study:
• No implant fractures.
• 95.8% implant survival rate, comparable with titanium.
• Simultaneous bone augmentations and/or sinus lifts did not impact survival rates
• The volume of keratinized gingiva increased over time.
• One crown and glass fiber post fracture reported, i.e., a prosthetic complication rate of 2.1%.
