외과 의사는 건강 문제가있는 경우 부비동 엘리베이터에서 환자를 거부 할 수 있습니다. 일반적으로 수술에 대한 금기 사항은 절대 및 상대적인 두 그룹으로 나뉩니다.

절대 금기 사항

여기에는 외과적 조작을 수행하기 어렵거나 임플란트 생착 가능성을 반복적으로 감소시키는 조건이 포함됩니다. 수술이 불가능한 경우:

  • mental disorders,
  • severe heart disease,
  • cancer,
  • tuberculosis,
  • blood clotting disorders,
  • autoimmune diseases (lupus erythematosus, rheumatoid arthritis, multiple sclerosis),
  • pregnancy.

Relative contraindications

임플란트 식립 시점에 쉽게 제거하거나 교정할 수 있습니다. 수술 결정은 환자에 대한 철저한 진단과 하위 전문 의사와의 상담 후 외과의가 내립니다.

상대적인 금기 사항은 다음과 같습니다:

  • diabetes mellitus (the operation will be done after the endocrinologist selects the correct treatment),
  • angina pectoris (the intervention is performed in remission),
  • rhinitis, acute or chronic sinusitis (the patient will be referred to an ENT specialist for treatment),
  • cysts, purulent processes in the oral cavity, tooth decay and gum disease (treated by a general dentist).

With caution, surgical intervention is performed on smokers, as they have worse healing of tissues. The risk of implant rejection is reduced if the patient stops smoking at least 2 weeks before surgery.

A contraindication to closed sinus elevator is a bone height of less than 5-6 mm.

How safe is a sinus elevator

Any surgical procedure is a health risk. A common complication of a sinus elevator is rupture of the maxillary sinus walls. The doctor can damage them while moving the bottom of the sinus upward. If this happens, the surgeon sutures the tear and completes the sinus elevator surgery. But if the tear is too large, the procedure has to be interrupted. It is attempted again six months later, when the sinus wall has healed.

Other complications:

  • infection of the bone substitute,
  • bleeding,
  • exacerbation of chronic inflammation of the maxillary sinus.

The risks of complications are higher in smokers, diabetics, and patients with immune disorders.

Alternatives

An alternative to sinus elevator is the placement of removable prostheses (burettes or plates) or basal implantation. Unlike classical implants, basal implants bypass the maxillary sinuses. They are placed in the deep layers of the jaw, which do not resorb over time. Therefore, the procedure is performed without prior bone augmentation. The only disadvantage of basal implantation is that it is used only in the absence of 3 or more consecutive teeth.
