I think it would be best to rejuvenate the laurel you already have there by some hard pruning - the laurel will soon bush out and fill the gaps. Then clear the ivy, feed and mulch the hedge to promote growth and if you feel unsure that it will bush out enough, you can buy a couple of bare root laurel hedging plants to plant and fill in the gaps.
Remember hedges shouldn't be cut back in the nesting season i.e. from February to mid July, so this is a job best done next autumn/winter.
