Clinical Recommendations 临床推荐
1）In fully edentulous
patients can a CIFDP or an IOD be recommended to provide optimal stability and
comfort?
1）对无牙颌患者，种植支持式全口固定义齿和种植覆盖义齿能提供理想的稳定性和舒适性吗？
In
fully edentulous patients, based on dPROs, both
CIFDPs and IODs result in an improvement in stability and comfort compared to
CDs. For the highest levels of stability, retention, and comfort, CIFDPs may be
recommended over IODs, whenever clinically indicated. Clinical decisions should
also consider other relevant factors including speech, esthetic concerns,
prosthetic space requirements, costs, stability, retention, maintenance
requirements, and manual dexterity. Continuous assessment of the patient's
ability to manage the prosthesis and maintain plaque control should be
performed.
对无牙颌患者，基于口腔患者报告结局，种植支持式全口固定义齿和种植覆盖义齿都能改善全口义齿的稳定性和舒适性。为达到最高程度的稳定、固位和舒适，只要符合临床适应证，种植支持式全口固定义齿比种植覆盖义齿更值得推荐。临床决策中还应考虑其他相关因素，如发音、美观要求、修复空间需求、费用、稳定、固位、维护需求、工艺熟练度。必须持续随访，评估患者维护修复体和维持菌斑控制的能力。
2）What is the ideal
attachment for a mandibular IOD?
2）种植覆盖义齿的理想附着体是什么？
What
is the ideal attachment for a mandibular IOD? In fully edentulous patients,
both splinted and unsplinted attachments are equally
effective from a patient's perspective and can be recommended.
种植覆盖义齿的理想附着体是什么？在无牙颌患者中，夹板式和非夹板式的附着体从患者角度都同样有效并值得推荐。
3）Based on dPROs, what is the ideal number of implants to
retain/support a mandibular IOD?
3）基于口腔患者报告结局，下颌种植覆盖义齿理想的固位/支持植体数量是多少？
Based
on dPROs, what is the ideal number of implants to
retain/support a mandibular IOD? In fully edentulous patients, mandibular IODs
retained by one or two implants show positive effects on dPROs
compared to a mandibular CD, with two implants being the optimal number.
Additional implants do not offer further improvements in dPROs.
Based on expert opinion, if the opposing maxilla is dentate or restored with a
fully implant-supported prosthesis, more than two standard-diameter implants in
strategic positions are recommended to support the mandibular IOD to avoid
complications and fractures of the implants and prosthetic components. More
than two implants are also recommended to enable implant support over mucosal
support in compromised anatomical situations (e.g., highly resorbed posterior
mandible) and/or compromised mucosal conditions (e.g., hyposalivation).
基于口腔患者报告结局，下颌种植覆盖义齿理想的固位/支持植体数量是多少？在无牙颌患者中，由一颗或两颗植体固位的下颌种植覆盖义齿，比传统下颌全口义齿有更好的口腔患者报告结局，其中两颗植体固位是理想的数量。进一步增加植体并不会更加改善口腔患者报告结局。基于专家意见，如果对颌为天然牙，或对颌全部为种植支持式修复体，那么推荐使用两颗以上的标准直径种植体在关键位置支持下颌种植覆盖义齿，从而避免种植体或修复体折裂等并发症。在解剖条件欠佳（如下颌后牙区重度骨吸收）和/或粘膜条件欠佳（如口干症）时，同样推荐使用两颗以上的种植体，从而实现更多的种植体支持而非粘膜支持。
