In short. The candidacy lines are drawn from tissue and anatomy rather than preference: bone projection, soft tissue cover, asymmetry and the profile relationship decide.
Key points
- Two patients can want the same option and be candidates for different ones, because the findings differ.
- That is not a judgement about either patient; it is what an examination is for, and it is the reason the same request can produce two different plans.
Candidacy for these two options is decided by anatomy rather than by preference, and the findings that decide it are all examination findings. The useful way to state it is not who is a good candidate in general but which finding each option answers.
Who an implant suits
A chin that is deficient at the bone, in a face whose profile would balance if the chin were projected. The soft tissue over the chin has to cover the change without the edges of the implant becoming visible, and the bite and the jaw relationship have to be normal, because a structural change made to correct a jaw problem does not correct it. Where those findings are present, the projection is planned against the profile.
Who filler suits
A minor step in the profile, a small asymmetry, or a chin that would read better with slightly more projection over the bone rather than a change to the bone. It also suits a patient who is unsure whether the change is wanted and would rather find out with something temporary, and one for whom being able to dissolve the result matters more than durability. It does not suit a chin genuinely deficient at the bone, because volume over a bone produces projection without changing the relationship.
The lines are drawn by findings, not by preference
Two patients can want the same option and be candidates for different ones, because the findings differ. That is not a judgement about either patient; it is what an examination is for, and it is the reason the same request can produce two different plans.
Who neither option suits
A patient whose profile imbalance comes from the nose or the lips, because adding to the chin changes a part of the profile that was not causing the appearance. A patient whose real finding is a bite, jaw or airway problem, which is a different specialty. A patient with a chin that is already prominent for the profile, because both options add. And a patient whose reason for treatment is another person’s opinion rather than their own, which is not a finding an examination can work with.
Why there is no age rule
There is no age at which either option becomes appropriate or inappropriate on its own. What matters is that growth has finished where the bone is concerned, that the soft tissue will cover the change, and that the patient is deciding for themselves. Those are clinical findings rather than birthdays, and a plan justified by an age threshold is justified by something other than the examination.
Where neither option is the right answer
- A profile whose imbalance is in the nose or the lips, where the chin is not the structure to change.
- A bite, jaw or airway finding, which belongs to another specialty rather than to this comparison.
- A chin that is already too prominent, and any plan whose real driver is another person’s opinion.
Candidacy here is not a matter of how much a patient wants the change. It is a matter of which structure is producing the appearance, and the answer decides which of the two options is relevant, or that neither is.
Frequently asked questions
What makes someone a candidate for an implant?
A chin that is deficient at the bone, with a profile that would balance if the chin were projected, and soft tissue that will cover the change without looking sharp or artificial. A normal bite and jaw relationship is part of it. Where those findings are present, an implant is a structural answer to a structural problem.
What makes someone a candidate for filler?
A minor step, a small asymmetry, or a profile that needs a little more projection than it has, with a chin that is not genuinely deficient at the bone. It also suits a patient who wants to see a change before committing to anything lasting, or who needs to be able to dissolve it.
Who is a candidate for neither?
A patient whose profile imbalance comes from the nose or the lips; a patient whose finding is a bite, jaw or airway problem; a patient with a chin that is already too prominent; and a patient whose reason for treatment is someone else’s opinion rather than their own. Each of those is better served by a different conversation.
Risks & Limitations
- No result can be guaranteed, and swelling must settle before either result is judged.
- An implant can become infected or move, and is removed only by a further operation.
- Filler is absorbed over months and the result is temporary.
- Neither option makes a chin smaller, and neither treats a bite or airway problem.
When to Seek Care
- Fever, or spreading redness, warmth or discharge around the incision or injection site.
- Severe or increasing pain, or a colour change in the skin of the lip or chin.
- Vision change or eye pain after a facial injection — this is an emergency.
- Worsening numbness or difficulty with the lip that was not there before.
