Edentulism presents an ongoing challenge for prosthodontic dentistry. Many aspects of complete denture construction lack contemporary evidence. One such aspect is denture occlusion. Balanced occlusion (BO) has become the prevailing occlusal scheme. It has been suggested that canine guidance (CG) is unsuitable for complete denture occlusion due to an increased risk for tipping of the prostheses. However it may be indicated in patients with minimal alveolus resorption. There has been limited evidence suggesting the superiority of either occlusal scheme over another. This article investigates the available literature assessing complete denture occlusion by means of clinical trials or reviews of evidence. We utilised PRISMA guidelines to investigate the effect of complete denture occlusal scheme (balance occlusion vs. canine guidance) on functional or quality of life. Seven studies were included for review. All studies were poor to moderate quality with the majority lacking randomisation, blinding and demographic data from the study sample. The available evidence suggests that the differences between occlusal schemes may be small, challenging the notion that BO may be the optimal occlusal scheme. There is a need for high-quality clinical research, investigating both chewing ability and quality of life in complete denture wearers in the long-term.
牙列缺失给口腔修复学带来了持续的挑战。全口义齿制作的许多方面缺乏当代证据。其中一个方面就是义齿咬合。平衡咬合（BO）已成为主流的咬合方案。有人认为，由于义齿倾斜风险增加，尖牙引导（CG）不适用于全口义齿咬合。然而，在牙槽嵴吸收 minimal 的患者中可能适用。几乎没有证据表明哪种咬合方案优于另一种。本文通过临床试验或证据综述来研究评估全口义齿咬合的现有文献。我们利用 PRISMA 指南来研究全口义齿咬合方案（平衡咬合与尖牙引导）对功能或生活质量的影响。纳入七项研究进行综述。所有研究质量均为差到中等，大多数缺乏随机化、盲法以及来自研究样本的人口统计学数据。现有证据表明，咬合方案之间的差异可能很小，这对平衡咬合可能是最佳咬合方案这一观点提出了挑战。需要进行高质量的临床研究，长期调查全口义齿佩戴者的咀嚼能力和生活质量。
