Simplifying the Treatment of Bone Atrophy in the Posterior Regions: Combination of Zygomatic and Wide-Short Implants—A Case Report with 2 Years of Follow-Up

Abstract

The rehabilitation of maxillary and mandibular bone atrophy represents one of the main challenges of modern oral implantology because it requires a variety of procedures, which not only differ technically, but also differ in their results. In the face of limitations such as deficiencies in the height and thickness of the alveolar structure, prosthetic rehabilitation has sought to avoid large bone reconstruction through bone grafting; this clinical behavior has become a treatment system based on evidence from clinical scientific research. In the treatment of atrophic maxilla, the use of zygomatic implants has been safely applied as a result of extreme technical rigor and mastery of this surgical skill. For cases of posterior mandibular atrophy, short implants with a large diameter and a combination of short and long implants have been recommended to improve biomechanical resistance. These surgical alternatives have demonstrated a success rate similar to that of oral rehabilitation with the placing of conventional implants, allowing the adoption of immediate loading protocol, a decrease in morbidity, simplification and speed of the treatment, and cost reduction. This case report presents complete oral rehabilitation in a patient with bilateral bone atrophy in the posterior regions of the maxilla and mandible with the goal of developing and increasing posterior occlusal stability during immediate loading.

Short implants (5‐8 mm) vs long implants (≥10 mm) with augmentation in atrophic posterior jaws: A meta‐analysis of randomised controlled trials

“…It is feasible to use short implants for overdentures in very old patients with severe alveolar bone atrophy . Wide short implants combined with zygomatic implants can also be used for patients with severe atrophic maxilla . For patients after head and neck tumour surgery, short implants can be used for edentulous occlusal rehabilitation caused by bone defect with contraindication of vertical bone augmentation .…”

Viabilidade do uso de implantes zigomáticos e implantes curtos em caso limítrofe: relato de caso

“…Paciente do sexo feminino de 62 anos leucoderma, retornou à Faculdade ILAPEO (Curitiba, PR, Brasil) após 11 anos, para retratamento da arcada inferior, anteriormente descrito por FAOT, F. et al 15 , cujas próteses fixas implantossuportadas apresentavam mobilidade. A arcada superior acometida por uma severa atrofia óssea e comunicação oroantral sugerida por exame radiográfico, foi reabilitada na mesma época por implantes zigomáticos, implantes convencionais na região anterior e uma prótese total implantossuportada do tipo protocolo híbrida sob carregamento imediato.…”

“…O objetivo desse relato de caso clínico é apresentar um retratamento de uma reabilitação total descrita anteriormente por FAOT, F et al 15 , no qual é discutido a previsibilidade dos implantes zigomáticos e implantes curtos.…”
