In the context of achieving good retention in a full veneer crown, applying a long path of insertion is highly beneficial. When a crown is designed with a long path of insertion, it allows for a more stable and secure fit over the prepared tooth structure. This technique helps in minimizing the risk of dislodgement due to the increased surface area contact between the crown and the tooth, which enhances retention.

Long paths of insertion are critical in ensuring that the crown can be seated accurately and efficiently. It helps in aligning the crown with the natural contours of the tooth, allowing for uniform distribution of adhesive forces. This alignment is essential as it reduces the potential for movement or misalignment once the crown is cemented in place.

In contrast, other methods may not provide the same level of effectiveness in terms of retention. For example, while parallel walls and taper can influence how well a crown fits, they don't necessarily optimize the retention as effectively as an appropriately designed path of insertion. Reducing taper significantly can create resistance but may also lead to complications with seating the crown properly if the design does not allow for an adequate path of insertion. Maximizing occlusal depth might alter the aesthetics and function of the crown but does not directly enhance retention in the way a longer path
